*django-cache-url* and *dj-email-url* recently partially changed their behavior. We should update our tests to reflect the changes. In detail, the following changes have been made: - [*django-cache-url* now uses djangos native redis backend for django>4](https://github.com/epicserve/django-cache-url/commit/1ad783f27d77e8c25847768524aeb7c6fa55695c) - [*dj-email-url* added support for the `EMAIL_TIMEOUT` setting which defaults to `None`](https://github.com/migonzalvar/dj-email-url/commit/a1f57a566f081b72620e4155b3fcda8b23ea08a6)
