Fix recents scale sometimes lagging behind window scale
We were previously offsetting the launcher animation progress based
on when we got onGestureStart, which meant it would lag behind if
onGestureStart came late. Now that we track the window instead of
the launcher shelf, and we don't show the launcher animation right
away in fully gestural mode anyway, we should remove this to ensure
the launcher part of the animation always lines up with the app
window.
We also reapply state whenever predictions are enabled, e.g. when
launcher starts after being force stopped, and previously this was
canceling the existing state animation. We don't want to do that
because predictions can be enabled at any point on a cold start,
and cancelling the existing state animation means that RecentsView
shows up in fullscreen and not attached to the app window for the
duration of the gesture.
