Fixed NullPointerException when Accursed Witch transforms (#5571)

* Fixed NullPointerException when Accursed Witch transforms

Feedback issue: #5529
Aura replacement code tried to remove the second face from the original zone which had ownerId == null. Now, we remember the first face (the original card) and remove it from the old zone before creating a permanent out of the second face.

* Accursed Witch's death trigger now requires targetting opponent instead of using aura replacement effects

Feedback issue: #5529
Previously you could attach Infectious Curse to either player and get around hexproof
The ability text has also been updated to match the Oracle text of Accursed Witch.
