Hello Mike. Today I took the road to upgrade from Django 1.6 --> 1.8. I wanted the bugfixes support and the long-term. Everything looked good at the very beginning BUT it turned out that I get the same error with you, concerning the "django_content_type" already exists. Have you found a solution to the problem?
