Steps to reproduce:
1. Check out to item to a patron and then check the same item in
2. Go to patron record, view closed loans
3. Click Anonymize all loans

Expected result: Loans are somehow anonymized. As a user I can't really tell from the description "Anonymize all loans" what this anonymization process will do (will the loans disappear from the list, or remain in the list but with details somehow masked), or how its outcome will be displayed or indicated. I expect to get some sort of visual confirmation of the success of the operation, maybe a "Loans have been successfully anonymized" modal.

Actual result: Closed loans now contains no loan data, only the phrase "The list contains no items" (as if the user had never checked anything out). It is not clear to me, however, what has actually happened. Has all data regarding the closed loans been purged, or only the link to the patron, or is it preserved in the system but not displayed in the patron view?
