 After a user login while working with [https://github.com/mozilla/mozilla-
 django-oidc mozilla-django-oidc], I came across this "DatabaseError:
 Forced update did not affect any rows" error on
 [https://github.com/mozilla/mozilla-django-
 
oidc/blob/71e4af8283a10aa51234de705d34cd298e927f97/mozilla_django_oidc/views.py#L112
 request.session.save()].
 This looks to me like a race condition where the session doesn't exist but
 
[https://github.com/django/django/blob/e1bbbbe6acb69e755554088bc573cc1835673209/django/contrib/sessions/backends/db.py#L87
 we still try to update it].
