Deliver latest intent extras to recents

Activity was destroyed when moved to background if
don't-keep-activities dev options had set. Swiping up
gesture would start recents behind top activity for recents
animation. However, the recents activity was restarted
With the intent which the activity was originally created, not
the latest intent came along with #startRecentsActivity().
