Fix bug 3167945 - list selection mode should persist across rotations

Browse Source 
Modal multi-choice mode action modes will now be restarted when
restoring instance state provided that the application has set a
multi-choice mode callback before instance state is restored. This
matches other list state restoration behavior with adapters.
