ImportError: Failed to find application, did you mean 'tests/test_integration:application'?

The issue is that the gunicorn process is inheriting the command line arguments used to run the tests and attempting to use them itself. I think setting sys.argv = [""] in the subprocess is the easiest fix (a bit hacky but it seems to work fine)
