Issue DM-5593: fix issue where butler repository search returns list for single item
Backwards compatible behavior is that when butler returns a single item, it is NOT in a list. A recent change (when the Repository class was added) broke this behavior. Change it back so that if an operation in repository would return a list with a single item, it pulls it from the list. Note this is only related to the case where a repository's parentJoin field is set to 'outer' and since no one is using this yet (they should not be, anyway) then the point is moot.
