Fix adjacent task positioning for consecutive swipe gestures

- Always use the recents scale down animation when coming from BACKGROUND_APP state
- Adjust scale down animation to calculate based on translationY = 0 instead of
  translationY > 0 if it is still set from a previous interaction
- Fallback to using launcher's insets in the case that a task doesn't yet have
  thumbnail data (we remove the data when the task stack is invisible, so it
  might not yet be restored if you swipe up again too quickly)
