While working I got a situation in which I wanted to open the side drawer on a button click. But I was not able to that. So I made some changes and now I am able to achieve the required functionality.

This prevented custom react views in navBar from being displayed if AppStyle was used.

* Fix style

* Fix resolving logic

* Fix styling

The only argument to `popTo` is the containerId to pop to, not the current containerId as well.  Also showing `this.props.previousContainerIds` lead me to believe that was included automatically (similar to `this.props.containerId`) so I changed that to avoid confusion.

The new path is `.../lib/ios` not just `/ios`

* animation fix

* fix tests

Since the docs suggested we remove everything inside the `didFinishLaunchingWithOptions`, without the return statement there was an `Control reaches end of non-void function` error since the function expects a boolean return. After adding this, the error goes away.

In the list of `LayoutTypes`, `tabs` is not defined, hence this throws an error. Replaced it with `bottomTabs`.

Fixes #1938 Closes #1900

This commit fixes two issues found in #1838. Fixes #1924
1. Keeps calling the deprecated reactInstanceManager methods when host is cleared
    to not introduce undesired behavior when clearHostOnActivityDestroy return true.
2. call onHostDestroy and onHostPause only if react context exists or is being created.

* remove unused code from tabStyle

* improve dummy screen ui

* set list screen translucent navigation bar

* make RCCToolBarView to composite the UIRootView inside

* add list screen for debug behaviours

* add dummy screen

* ui changes in ListScreen

* add push list screen function without add it to the button to the screen

* add and comment push list screen row

This only happens when you are using react-native@0.48.3, and your XCode is in version 9.0
