Remove member from non-existent global group
When creating same group name in future, previous member become a new same group name member.
for avoid this, I will remove member from non-existent global group.
MariaDB [centralauth_p]> SELECT * FROM global_user_groups WHERE gug_group NOT IN (SELECT distinct(ggp_group) FROM global_group_permissions GROUP BY ggp_group); +----------+----------------------+ | gug_user | gug_group | +----------+----------------------+ | 99 | Cabal | | 575 | URL-upload_(testing) | +----------+----------------------+ 2 rows in set (0.01 sec)
