Bug description

HI,
we have created several user groups and had to rename one of them. that worked fine.

But when we edit a user and want to add/remove him to a group - or when we go to apps and limit an app to a specific user group - then those selections / dropdowns still show the old name. - it looks like renaming does not rename all the instances of the group-name. at some places the old name is still used and referenced.

Steps to reproduce

quite a long time ago that we renamed it and just stumbled across the problem.

so i guess it works like this

1. create a user group
2. rename it
3. assign it to a user - you will find the old name.

Expected behavior

new name should be used everywhere.

Nextcloud Server version

32

Reproduce this on Nextcloud Server 32 by creating, renaming, and then assigning a user group, including through app-restriction selections. Start with the user-edit and app-group dropdown entry points; done means the renamed group appears consistently and the old name no longer appears after the rename.
