Fix right split screen app going to wrong target

- applyWindowToHomeRotation() to both Matrix's individually
- Move matrix.postTranslate(mSplitOffset) into applyWindowToHomeRotation so it applies both during swipe up and animation to home

Test: Swipe up from vertical and horizontal split screen, ensure both app windows go towards the same target
