Backport #23154
There have been a number of reports of PRs being blocked whilst being checked which have been difficult to debug. In investigating #23050 I have realised that whilst the Warn there is somewhat of a miscall there was a real bug in the way that the LevelUniqueQueue was being restored on start-up of the PersistableChannelUniqueQueue.
Next there is a conflict in the setting of the internal leveldb queue name - This wasn't being set so it was being overridden by other unique queues.
This PR fixes these bugs and adds a testcase.
Thanks to @brechtvl for noticing the second issue.
