Default implementation causes `NotImplementedError` on Windows with
Python 3.8, because they changed default eventloop in 3.8.
NOTE: We do the same thing in the `example/settings.py` because it
imports (and fails) before we have a chance to invoke this fixture.
So, we could avoid adding this fixture, but I feel it is better to
keep the proper solution here as well.
