Move doze animation until finished waking up

Move the start of the LOCKSCREEN_TRANSITION_FROM_AOD animation from
onStartedWakingUp() to onFinishedWakingUp(). This mitigates against
dropped frames in sysui due to the animation running while HWC is
chaniging the power mode (see: IComposerClient.setPowerMode).

Test: wake up with/without power button, with/without touch to unlock
anytime enabled
