Tobias Reischmann 9bd6807635 MDL-60669 forum: Added duplicate check for restoring forum subscriptions ...

Before MDL-59854 it was possible to have duplicate forum subscriptions.
Trying to import backups created from back then, caused a DB exception
due to unqiue key constraints. Now only one of multiple identical forum
subscritions is restored.
