Align the end time of wallpaper rotation transform to its target
That fixes the flicker when backing from a different orientation
activity than home. Because the wallpaper window may be updated
later than home's transition. Ideally, the fixed rotation transform
of wallpaper should be synced with its target for consistency.
Also fixes various hidden errors of RecentsAnimationControllerTest.
Mostly about mDisplayContent:
- It is not default display so it requires additional mock.
- It contains many testing windows from default setup, that may
disturb the test flow.
- Currently it cannot rotate due to wrong condition in
TestDisplayContent.Builder.
That leads to several false positive results. Now it is changed to
use the existing default display and home stack, which is more
efficient and reasonable.
