Start AOD transition a frame earlier

During J<LOCKSCREEN_TRANSITION_FROM_AOD>, relayoutWindow was being
called twice. The second call was due to scrim property changes that
were delayed a frame because the ValueAnimator started from 1.0.

Test: During J<LOCKSCREEN_TRANSITION_FROM_AOD>, check that there is only
      one call to relayoutWindow
