Passing UndoInfo is not needed anymore when undoing the move

Browse Source 
We store it now in the same UndoInfo struct as 'previous'
field, so when doing a move we also know where to get
the previous info when undoing the back the move.

This is needed for future patches and is a nice cleanup anyway.

No functional change.
