Add a synchronous path when finishing a pre-existing recents animation
- If launcher repeatedly starts the recents animation, we try to finish
the existing animation before starting the new one, but due to some
ordering issues (see b/275561141) the subsequent starts can orphan
the previous animation runner, which can result in no animation callbacks
for either the previous animation (to cancel) or the new animation
(to start).
This change only attempts to reduce the likelihood of a second no-op
transition by synchronously finishing the existing recents animation
on the launcher side prior to starting the next animation.
There is one case this doesn't handle, where if the previous
onAnimationStart() has not been called back, then we can't directly
call the controller to finish, and need to rely on the no-op handling
on the shell transition side to handle the gesture.
