My last PR introduced a migration to blobs, changing them from being unique per cid to being unique per cid+user. This is because two users can upload the same blob, get the same cid, and then previously in tranquil the second user would never actually get their ownership recorded, meaning listBlobs was missing the blob, and a migration _off_ of tranquil would leave them sans blob https://tangled.org/tranquil.farm/tranquil-pds/pulls/261/round/3
This PR attempts to add a job to repair existing instances where blobs have been deduplicated and not attributed to each owning user. It does this by pulling all records for each user, and then in batches crawling the records to find blob references. For each blob reference, it checks whether that user has its ownership recorded, and if not, repairs it by adding the entry.
To avoid re-running this potentially heavy job on every startup, I've used the config table to store a little record of whether it has been run.
