Check for existence of the group when adding a user.

The Managed Entries plugin will allow a user to be added even if a group
of the same name exists. This would leave the user without a private
group.

We need to check for both the user and the group so we can do 1 of 3 things:
- throw an error that the group exists (but not the user)
- throw an error that the user exists (and the group)
- allow the uesr to be added
