django-rest-auth v0.9.3 leads to ERROR: relation "django

On an existing application running tests with v0.9.2 and v0.9.3 gives different results.

No other changes apart from upgrading django-rest-auth were made.

I have django-rest-auth[with_social]~=0.9.2 in requirements.txt.

/my_project # python3 manage.py test
Creating test database for alias 'default'...

Traceback (most recent call last):

    return self.cursor.execute(sql, params)
psycopg2.ProgrammingError: relation "django_site" does not exist


The above exception was the direct cause of the following exception:

Reverting to v0.9.2 fixed this.
