* fixes #22819 The old way fired a DELETE statement on each destruction of the DBLockingProvider. Which could cause a lot of queries. It's enough to run this every 5 minutes in a background job, which in the end could result in file locks that exists 5 minutes longer - in the worst case and for not properly released locks. This makes the DB based locking a lot more performant and could result in a similar performance to the Redis based locking provider.
