* Fix topBar.noBorder option on iOS 13

* Fix unit tests

* empty commit

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.

React view title layout didn't recalculated it size on orientation change which caused it to look bad on iPads.

Though icon is required on Android when declaring tabs, it's optional when calling mergeOptions to update tabs.

When BottomTabs are hidden, draw components behind the tabs even if drawBehind isn't set to true explicitly.

This option is used to force large icons to be displayed when only three icons, without titles, are present on the screen.

For some reason layout direction isn't propagated to subviews correctly in the Wix app.
This commit is mostly a workaround, it sets the layout direction on the ViewGroup containing TopBar buttons
so that they appear in the right order in RTL.

Looking at the docs (1581780d2c/docs/docs/styling.md) and code (1581780d2c/lib/ios/RNNSideMenuSideOptions.m (L11)) it's possible to use the shouldStretchDrawer property on sideMenu. This property was however missing in the TS interface.

Edge case when preDrawListener callback is invoked after ViewController is destroyed

When mergeOptions was called without a title component, existing component was undesirably removed.
This commit changes how component is removed when mergeOptions is called. It will now be removed if a component is not defined and title is defined in mergeOptions.
Fixes #5628

When updating a tab icon, if null was used as color - it would get applied.

Add docs for bottomTab requiring icon on Android

This new updateProps command allows to update props for a component registered with Navigation.registerComponent.
The updated props are handled by shouldComponentUpdate and componentDidUpdate lifecycle methods.
This commit builds upon the work done in 291f16177d and is a breaking change.

Add support for NavigationBar color on Android

This commit adds support to update props of screen or custom button/title via the mergeOptions api.

Navigation.mergeOptions('myComponentId', {
  passProps: {
    text: 'new value'
  }
});
