fix(django1.10): Fixing cache_version not being set

- This is currently breaking things when we retrieve objects from cache
  since the version is no longer being set. Resulting in inconsistencies
  between setting and getting objects.
- In django1.10 it seems that we no longer will get the same object
  manager as the original one from the app registry process.
