Set occluded = false if occlude remote animation is cancelled.

Due to a bug, this was previously not needed (and could
cause issues) since WM would call setOccluded(false)
directly if the animation was cancelled. However, that
was due to a flag mismatch bug fixed in ag/17776445.

With that bug fixed, WM is never expected to call
setOccluded directly, so we need to do it when the
animation is cancelled.
