Dungeon :"Scarlet Monastery" doesn't work for Death Knights

Bug description: Even after i finished the Death Knight scenario where you have to ressurect Whitemane , the dungeon "Scarlet Monastery " Classic and Mists of Pandaria versions are unavabile to enter because somehow the scenario is still active and when you enter it teleports you in the scenario and not in the "old" instance.

confirm, throw in the old instance. The change in the complexity of the dungeon does not affect anything
