Back-end bug.

FYI for new developers:

There is a /api/delete_blockers/ endpoint that tells front-end if a given resource can be deleted, or if some other resource depends on it.

That endpoint returns no blockers for this record:
https://herbrbge-edge.test.specifysystems.org/api/delete_blockers/borrow/1365/

Need to figure out why it doesn't report this dependency as a delete blocker

Until then, a workaround is to manually delete the related records or make them reference a different borrow record.

Not solved by #2806
