    Sprinkle some more connection_adjust_for_autogap()
    
    Review after bug 697741 and:
    
    * move_handle() method needs to call connection_adjust_for_autogap() after

        * objects/UML/constraint.c objects/UML/implements.c
          objects/UML/message.c objects/Jackson/phenomenon.c
          objects/KAOS/metaandorrel.c : move_handle() method needs to call
        connection_adjust_for_autogap() after connection_move_handle() because
        the endpoints used for relative text movement need adjustment after
        possible autogap correction.
