Update Django message ref example for 1.11, fixes #993

- Use a `TemplateResponse` (backwards compatible to Django 1.7)
  instead of trying to pass a `Context` object to an instance of

  no longer allowed (see #993)
- Verified working with example app (Python 3.5, Django 1.11)
  before changing example in docs
