Title: remove groups from default permissions when removed; bug in group_add_member

Groups weren't being deleted from a user's default permissions when the group was removed. That made it look like new posts were continuing to be posted to the old group.

Also, one of the DB fields was wrong in group_add_member, which occasionally caused a weird bug where a contact could be added to a group multiple times
