[GAMEPLAY] Mordekaiser is able to have both the Dragon Ghost and a Champion Ghost

When Mordekaiser cursed the dragon while already having the ghost of a champion, the Dragon Ghost did not replace the ghost of the champion (picture attached).

1. Use Mordekaiser's ult to enslave a champion's ghost.
2. Curse the Dragon to enslave its ghost.
3. The Dragon Ghost may not replace the champion's ghost, and you will have two ghosts.

There was never a chance to test if the bug was recurring during the game, so I'm not sure if it was a 1 time thing or not.
