f3fb3c6f56When adding Avatar email-hash pairs we simply want the DB table to represent a Set. We don't care if the hash-pair is already present, so we just simply Insert and ignore the error. Unfortunately this seems to cause some DBs to log the duplicate insert to their logs - looking like a bug a in Gitea. Now, there is no standard way in SQL to say Insert but if there's an error ignore it. MySQL has INSERT IGNORE, PostgreSQL >= 9.5 has INSERT ... ON CONFLICT DO NOTHING, but I do not believe that SQLite or MSSQL have variants. This PR places the insert in a transaction which we are happy to fail if there is an error - hopefully this will stop the unnecessary logging.
