Dianne Hackborn b677746bd8 Change recents UIs to do task switches.
When switching to a recent task that is currently active, do a
task switch instead of a start activity, so the activity is brought
back in its exact same state.

Also fix problem in phone recents where the icon would disappear
after you touch it.
