Admin member count is off on groups page

[awesomerobot (Kris)]

Possibly related to Group administration: inconsistent number of members shown if some members were removed - #8 by zogstrip

Visit /groups

Then visit /groups/admins

and /admin/groups/automatic

Maybe discobot/system are getting picked up in the count and not filtered out from /groups?

I fixed the queries so we don’t count anymore
