all the possible flags. The same applies to "coverage html" and
"coverage xml".

Thanks Andriy Sokolovskiy and Simon Charette for the review.

HttpRequest.urlconf is set to None, rather than raising

rather than just relying on manipulation of settings to determine which
invocation of connection.cursor() opens a connection to the test database
and which opens a connection to the main database.

Thanks Aymeric Augustin for motivation and Tim Graham for review.
