crash when you undo a move (or copy). this regression was caused by two checkins (#59694 and #166411) the fix is to move the code that sets the src and dest keys on the undo transaction back to where it was and to bullet proof the undo transaction code so that if we don't have any src keys. r=cavin, sr=bienvenu, a=asa git-svn-id: svn://10.0.0.236/trunk@138061 18797224-902f-48f8-a5cc-f745e15eee43
