If the user has requested that dreams start when docked and a user activity timeout occurs, then start dreaming assuming all of the other usual conditions are appropriate for dreaming (the device is powered, etc.). Previously dreams only started when the device was initial docked but not if the device fell asleep while remaining docked. Bug: 7281240 Change-Id: I72c3f854fd1ae8e6615f4fa6e4c4ecd8de37c84b
