Harden light reveal transition logic
The previous code assumed a continuous order of transitions emitted by
the transition framework. Meaning if X -> LOCKSCREEN the next transition
has to be LOCKSCREEN -> Y. While this assumption is still correct, we
have seen bugs in transition code that would sometimes skip one of
these transitions. For these cases we could end up in a state where the
animation would have been skipped and all subsequent states are
revealed, therefore `willTransitionChangeEndState(it)` would block all
further calls from revealing the scrim.
The new code does not rely on this assumption and will attempt to repeat
the reveal animation if we are not in the desired reveal state and the
animation is not yet running.
