uilib is used only in the playground app and was added by mistake to dependencies.

* Add -UseModernBuildSystem=NO for xcodebuild

* Add -UseModernBuildSystem to detox build

* Cleanup and reorganise playground app

* Separated tests into three categories
  1. Layouts - layout specific tests and feature showcase
  2. Options - options related tests; interactions between static and dynamic options, merge options etc
  3. Navigation - general navigation features; Orientation handling, events, Overlay etc

* Fixed a few Android bugs
  1. testID wasn’t applied on TopBar react buttons
  2. static options were disregarded when creating initial BottomTab options
  3. Trying to open a none existent SideMenu would result in a crash

* Fix e2e tests

* Fix lint

* Few fixes + split push from SideMenu test into two tests

* Fixes e2e

Played around with context api, tried to get the wrapped component to rerender after global context
was updated - this is what I came up with.

Note: this commit makes the playground app use a newer js core as the js core which shipped with RN on Android
is missing javascript Proxy.

Closes #4517

- `registerCommandListener` documentation was wrong so that is fixed
- use `uniqueIdProvider` much as possible so we are not duplicating logic
- add `appRegistryService` which makes `componentRegistry` cleaner and also makes testing easier
- type return type of `NativeEventsReceiver.ts` correctly
- add types to `LayoutTreeParser`
- `ComponentRegistry.test.tsx` refactor so it tests only things that is should and not implementation of React Native functions
- fix type `center` prop to be required on `LayoutSideMenu`
- add missing layout props `topTabs` and `externalComponent`
- lots of minor cleaning

The following PR introduces improved support for Context api and other api's which wrap the root view.

## Context api
Navigation.registerComponent('navigation.playground.ContextScreen', () => (props) => (
  <TitleContext.Provider value={'Title from Provider'}>
    <ContextScreen {...props} />
  </TitleContext.Provider>
), () => ContextScreen);

## Redux
Navigation.registerComponent('navigation.playground.ReduxScreen', () => (props) => (
  <Provider store={reduxStore}>
    <ReduxScreen {...props} />
  </Provider>
), () => ReduxScreen);

## Plain Component - not changed
Navigation.registerComponent('navigation.playground.MyScreen', () => MyScreen);

This PR also upgrades the TypeScript version to 3.2.0 and RN version used in the playground app to 0.57.7

* New Android build flavor - `reactNative57_7`
* Unit test coverage is disabled, for some reason it broke after upgrading to RN 0.57.7

I needed to update the package in order to build the playground project.

* Fixes overlays level - #4145

* Disable overlay unmounts when dismissed

* Fixes e2e

Implement Element transition on Android

This commit adds basic support for Element transition to Android.
Currently, only Shared Transition is supported and only when pushing screens.

There are a few caveats you need to be aware of if you intend to use
this feature in its current state:

1. Since elements need to be laid out before the transition can start, Set `waitForRender: true` when pushing the destination screen.
2. Fade animation has to be used when pushing screens with shared elements.

API

```js
options: {
  animations: {
    push: {
      waitForRender: true,
      content: {
        alpha: {
          from: 0,
          to: 1,
          duration: 250
        }
      }
    }
  },
  customTransition: {
    animations: [
    ]
  }
}
```

This commit also upgrades TypeScript to version 2.9.x

* test

* Added jest coverage reporter html for Jenkins

* Migrate to jest to support parallel ios simulator from detox

* When e2e lint only ts or js files

* Remove mocha from deps and decrease from 480000ms to 180000ms

* Support RN 0.55.4

This commit adds support for RN 0.55.4 by introducing version specific build flavors - reactNative51

* Update scripts after introducing build flavors

* Update Android installation instruction on specifying build flavor
