fix(Android): prevent crash by properly managing lifecycle of the dimming view

[kkafar]

Description

When we have a formSheet on Android & we navigate to regular push screen on top of it & we go back navigation.goBack()
the app will crash.
This is because the ScreenStackFragment' view will be recreated, but it will reuse existing dimming view, leading to a crash when
inserting this dimming view to a coordinator, because no one never cleared previous parent of it.

Changes

See the code, basically I've ensured that the previous dimming view is invalidated & on fragment view recreation (when it is reattached)
new dimming view is created.

Test code and steps to reproduce

TestFormSheet

1. Open sheet
2. Navigate to second
3. Go back
4. In this very moment app crashes
