Added Tastypie-specific data to MySQL dump.

refs #4658

If django.contrib.auth is in INSTALLED_APPS then Tastypie will enable a feature
where users can have API-specific permissions granted to them. The feature expects
certain database tables and data to exist, however, and normal user management
in Django will throw errors if these tables/data aren't present. These is no
way currently to disable this functionality in Tastypie without disabling
django.contrib.auth.
