This provides a quick fix for http://b/2298803 (if the in-call UI comes up while the user is holding the windowshade, the shade sticks in place and the display becomes unresponsive). Merged from master (I92a824fe). TODO: safely restore code to animate the shade closed rather than simply causing it to disappear. Change-Id: I53dc76fdfe86636f30f37a223a88d27a5766d3eb
