    Fix for failing gates

    We were launching the tests using run_tests.sh
    with flag 'V' set, which makes the tests beeing run
    in the virtualenv. However, the tests are already beeing run
    in virtualenv since they are beeing run by tox. So we
    basically made virtualenv inside the virtualenv.
