Bug 37349: Use cache for authority types and remove extra fetch

This patch caches the authority types when fetched during linking to avoid grabbing the same type more than once.
Additionally it removes a second call to fetch the same type in some scenarios

To test:
1 - Apply patch
2 - Enable linking during cataloging/updating records
3 - Edit a record and confirm it is linked ocrrectly
4 - Run the authority linking cron and confirm it works as expected
