Title: show error messages if failed to add user

When I run ```RAILS_ENV=production script/add_user.sh -u test -p test -m 'email@domain.com'``` it shows that the user is added. But in fact the password is too short and the ```add_user``` is failed. It's a bit confusing.

I think if the operation fails, we should let users know what exactly has happened.
