Subject: [PATCH] [Audio] Catch unhandled internal folder types (#2824)

The `folder:` and `localfolder:` prefixes are used internally with some localtracks strings to define what to do with the item when it's cycled through the search function. Users theoretically should have never seen this issue as [p]search is used on the user side for YouTube and Soundcloud searching and not local searching, but this handles the issue where a folder is being passed to these functions that doesn't exist.
