Fix KState extraction

Summary:
The field changed from mStates to states breaking our reflection based code. Ideally I would like to just check if type == KStateContainer and access the field normally but the rest of the infrastructure expect to work on a java field.

Added tests to catch this sort of thing in the future. had to shift buck files around a bit to get it to work
