Bug description

A group admin can see all users that are in at least one of his administered groups under /settings/users.

In the user table in the column "Groups" all groups are listed which the respective user is in.

For groups that are not administered by said group admin, the plain group name is displayed instead of the group label.

Steps to reproduce

1. Create some users and some groups
2. Rename the groups, so they are getting a label that differs from the group name
3. Make one of the users group admin of some (but not all) the groups
4. Log in as that group admin user and go to /settings/users

Expected behavior

In the user table in the column "Groups", the group labels should be used for all groups.
