Subject: gnu: django: Fix the build for python-django-gravatar2.

The build was failing as the Django settings were not configured for the
tests. The relevant files are missing from the release on PyPI, so switch to
using a more complete source release. Also update the package at the same
time.

* gnu/packages/django.scm (python-django-gravatar2)[version]: 1.4.0 -> 1.4.2.
  [source]: Change to use a tarball from GitHub, update the sha256 hash.
  [arguments]: Add a phase to skip a test requiring network access, and
  replace the check phase to call ./manage.py within the example_project
  directory.
