Safety check for OCCLUDED on wakeup

There is a rare case where on device wakeup, occlusion also starts
as during a phone call. If these signals come in at just the wrong
time, the existing FromAodTransitionInteractor will decide to go
to LOCKSCREEN. This adds a failsafe check to ensure any transition
to LOCKSCREEN gets redirected to OCCLUDED if need be.
