Native Animated - Restore default values when removing props on Android

Browse Source 
Summary:
Same as #11819 but for Android. I didn't notice the bug initially in my app because I was using different animations on Android which did not trigger this issue.

**Test plan**
Created a simple repro example and tested that this fixes it. https://gist.github.com/janicduplessis/0f3eb362dae63fedf99a0d3ee041796a
Closes https://github.com/facebook/react-native/pull/12842
