Contacts app shows user id instead of display name for the members

cc @daita
but you can call me e404
This is fixed on master:
- run
./occ circles:maintenance --level 5to upgrade alldisplayName - editing an Account should upgrade the displayName of the Single Circle and all Members related to the UserId/FederatedUser
- should also works in GlobalScale setup
For me, the problem still exists. (NC23)
When I add a user to a circle, username/userId is used as displayName. But when the user updates their display name, the userId is replaced with the display name.
So it seems that the cache is not initialized properly.
I have added ./occ circles:maintenance --level 5 to my crontab. Is this supposed to be triggered by the main cron.php from Nextcloud? At least in our Nextcloud 25.0.1 with Circles 25.0.0, names remained strange for weeks, even though cron.php is triggered once every 5 minutes.
