When someone starts new ref-distro and don't want to use demo-data profile there is no way to log in as admin user because there are no user contact details in notification service for this user.
1. Start fresh ref-distro with spring_profiles_active set to production
2. Go to log in page
3. Try to log in as admin
4. Log in fails because of lack of user contact details.
Ideally, in notification service, there should be a migration with user contact details for admin user.
