cookiecutter-django: Unknown field(s) (first_name, last_name) specified for User in admin

What happened?

I created a new cookiecutter-django project and went through the steps here to get started. Then I created a superuser and logged in, but when I click on the edit user link from the admin view I get the following error:

django.core.exceptions.FieldError: Unknown field(s) (first_name, last_name) specified for User. Check fields/fieldsets/exclude attributes of class UserAdmin.

What should’ve happened instead?

Instead I should have gotten to the edit user admin page.
