fix(android): check if selectedItemId has changed before setting

[johankasperi]

Description

onNativeFocusChange is called on android after closing a screen "on top of" a screen having bottom tabs. This is because we are setting bottomNavigationView.selectedItemId in updateBottomNavigationViewAppearance even though it have not changed because onNavigationItemSelectedListener is notified on reselect

This differs from the implementation on iOS (where onNativeFocusChange is only called on tab press) and creates some problems. For example will "tab press" be emitted in react-navigation causing the scrollview in the tab to scroll to top after closing a modal. Or if there is a nested stack in the tab, the stack will pop to the route on index 0.

Changes

Check that selectedItemId has changed before setting it to bottomNavigationView.selectedItemId
