Fix modal dismissed with swipe gesture emits wrong componentId

* Remove main window backgroundColor
* Better interface for TopBarPresenter

Fab has been broken since v3. This is a very temporary fix until we refactor it and upgrade to fab from AndroidX

Improved attach mode together unit test

Add iOS support for `bottomTabs.attachMode`.
This property controls when BottomTabs children are attached to hierarchy and when their React views are created.

By default, RNN attaches all children at the same time which might impact loading time as a few screens are instantiated at once.
Using `afterInitialTab` or `onSwitchToTab` generally leads to improved start up time.

Since migrating to CocoaPods, we had to pod install to compile local changes - using legacy build system works around that.

* Fix dismissed modal event by swiping down gesture

* Fix typescript

modalsDismissed was missing from event declaration. This obscure property represents the number of modals which were dismissed. When dismissModal is called it's 1 and when dismissAllModals is called, it's the number of modals which were visible on screen.

Hey, it is me again 🙂So I am just updating the docs due to some changes to my [starter](https://github.com/kanzitelli/react-native-navigation-starter) which are upgrading RNN to v4 and adding implementation of app logic using [MobX State Tree](https://github.com/mobxjs/mobx-state-tree) as an alternative to Redux.

When updating buttons with mergeOptions, existing custom buttons are unmounted and then recreated. This commit adds an optimisation which prevents the react components from being recreated.
To avoid unnecessary recreation, add an `id` to the component. If an existing react view is found for that id, it will be reused.

For some reason, AHBottomNavigation has two background color properties - backgroundColor and defaultBackgroundColor. Sometimes the default background color is applied, which causes the BottomTabs to be colored white.
