Omits the test folder since checking coverage of the test functions
themselves makes little sense.

The Django configuration expects a static directory to be present
on the file system, otherwise the tests will output a warning.  This
adds an empty directory using the clever git trick of ignoring
everything within the directory except the .gitignore file itself.

This silences a warning during the test run.
