Old ones must be put in undo list, and the new ones can be modified by clean up

If an abord command is made, old wires must be put in EEDrawList, and copies must be deleted
This is because previously stored undo commands can handle pointers on wires or bus,
and we do not delete wires or bus, we must put they in undo list.
Because cleanup delete and/or modify bus and wires, the more easy is to put all wires in undo list
