fdd5c923ed use only maxres if there is a lexicographic objective, fix #6697 
- maxlex.enable heuristic does not work if it is chained among multiple objectives. Only maxres is set up to commit the proper constraints.

e844aef896 remove a few more copy constructors, though still not enough to enable the assertion in vector 
I give up for now; there are too many copies left for little return..
