4.5.2: Random mayan.apps.lock_manager.exceptions.LockError

Continuing from #1154 (closed):

I retitled #1154 (closed), because the title obviously was incorrect (the error has no relation to webform upload, but appears randomly without interaction with the running application). I was told to rather create a new issue, so here we go with a more appropriate title. The app is unresponsive after the error and the docker container has to be restarted.

The traceback is very much the same:
