Webserver fixture timeout is causing intermittent test failures

[b4handjr]

Our webserver fixture that is used to serve notifications for our tests is sometimes causing the tests to fail due to a ConnectionReset Error.

=================================== FAILURES ===================================
___________ test_progress_notification_downloading[firefox_options0] ___________

browser = <foxpuppet.windows.browser.window.BrowserWindow object at 0x7fa3ccc51520>
progress_notification = <foxpuppet.windows.browser.notifications.addons.AddOnProgress object at 0x7fa3ccc35010>

    @pytest.mark.parametrize(
        "firefox_options", [{"page_load_strategy_none": True}], indirect=True

This isn't causing our tests to fail, as the server will still serve the request.
