[Bug]: "Limit to groups" only finds former name when group was renamed

Bug description

If a group is renamed, "Limit to groups" takes the old group name, which seems to me like an id. However, if a group is renamed, it cannot be found by the actual name, which seems to me like a label, but with it's old name (serving as id). The old name can be seen in the URL when selecting the group in the "Users" section. However, this is a bit confusing since the rest of the GUI follows the label name of the group and the old name of the group needs to be known to select it.

Steps to reproduce

1. Create random group like "original_group"
2. Rename group to other name like "changed_group"
3. Go to Apps section and find an app that allows limiting to like "Polls"
4. Check box next to "limit to groups" and try to search for "changed_group" in the text field.
5. Then try to search for "original_group" - this will be found.

Expected behavior

If you search for the renamed group name to find that one.

Additional info

No response

No files or tests are identified in the issue. Reproduce the renamed-group search from the Apps section, then trace the “Limit to groups” entry point and compare how the displayed name and lookup value are supplied; done means searching for the new group name finds the renamed group.
