Changed behaviour of the wallpaper picker.
When opening the picker, the currently chosen wallpaper is shown in the background. In this change also the nullpointer was fixed when deleting the currently selected wallpaper and setting it, because we revert to the old wallpaper in that case. When going into the same live wallpaper than the currently selected we are going back to home if the user sets it or goes back now, in order for the user not to loose state. The real fix for this will be done later when the following bug will be fixed: b/13241760 Bug: 12063773 Bug: 13219612 Change-Id: I7c6abb25755eca99c3255278e0884d1ff4749b55
