Subject: [PATCH] add null check for keyboardFrame variable in
 KeyboardAvoidingView component

Summary:
This is a critical change and should be pushed to stabel asap

The reason for the pull request is to prevent crashes that can occure if the function relativeKeyboardHeight(keyboardFrame: ScreenRect) got null as an input variable which sometimes does happen.
