Prevent unnecessary reordering of the home stack
- Just cancel the recents animation in-place when handling the home button
to prevent it from being repositioned to the bottom (which stops home)
and then starting it again (which restarts it)
Bug: 74405472
Test: Press home from an app, ensure launcher stop is only called once
