Fix lockscreen anim not running on unlock with FPS

For side FPS devices, it is possible for the device to be waking up
and also dreaming. If this happens a
BiometricUnlockController.MODE_WAKE_AND_UNLOCK_FROM_DREAM is
sent. This will then take path that assumes the lockscreen content
will be hidden immediately, as if from AOD. This isn't the case for
side FPS devices, where the animation still needs to run.

Test: atest KeyguardUnlockAnimationControllerTest
Test: manual - This is a timing issue. Unlock with side FPS over and
over again to ensure the animation runs
