Another attempt to fix the select-reference-point toolstack thing.

This time remove the push/pop from the picker tools as that's
responsible for the issue of trying to re-activate the move action
when its popped.  Instead do the push/pop from the client code
of other actions that need it, and not at all from the move-with-
reference action.
