Title: Bug 819893 - [Gaia::Clock] Unable to close or snooze alarm after an user kills Clock app by Window Manager

1. We just prevent people from closing the app with a attention screen from the cards view.
2. User still can drag the each cards view. If the app has a attention screen, user cannot kill the app with swipe event.
