Bugfix: Ignore sound fadeout requests on retired sounds Because sound is a shared-ownership resource and we have scenarios where owners don't know that the sound sometimes has been retired, we need to be a bit more permissive with existing cleanup logic. Tests: Had a fish bite with the fishing rod, started pulling then switched over to a different item, then tried fishing again - with sound pooling this would sometimes throw, but not anymore. Confirmed with audio logs that bad scenario did happen but didn't fail.
