Fix missing autoupdate (when group changes in participant list)

[Elblinator]

Current behaviour:
If you remove your admin status via the edit detail dialog (in the participant-list click on the group names of your participant), the dialog opens correctly, but afterwards you can still open this dialog but not change anything in it.

Recreation:
in a meeting:

1. login as a (normal/only) meeting-admin
2. go into the participant-list
3. via the edit dialog remove your own admin-right
4. open the dialog again (correct behaviour would be that you cannot open it again)

Wanted behaviour:
the edit detail dialog should only open if you are allowed to manage participants
