AppListControllerImpl: if overview mode starting animation was
canceled, the overview is about to start exiting, so update app list
visibility accordingly - app list will not be occluded by overview, so
its visibility should be determined by whether any windows are
visible (this avoids changing the app list visibility to false for a
moment before overview exit starts).

In ShelfLayoutManager do not reset workspace update blockers as another
overview animation is about to start.
