Handle fixed landscape activity in Bubble when folded.

If isStayAwakeOnFold is active, a Bubble with a top fixed landscape activity will launch to fullscreen.

Note: If isStayAwakeOnFold is not active, the behavior will remain the same. The Bubble with a fixed landscape activity will remain on the screen but launch into fullscreen when tapped: http://screencast/cast/NDUyOTI4NzYzMjc4MTMxMnw5NGNlODg2ZC04Mw
