@Katherine-Osos, @PaulKuykendall or @katypies should this one actually be in m7 for notifications?

Adding the refinement label because these emails are supposed to be sent when a person is invited via the registrar OR Django admin. This ticket should be updated to account for the existing work that was done in this ticket. Also, we may want to wait until the "add a member" workflow has been finalized. cc: @abroddrick
