[tor-commits] [stem/master] Move test's ownership connection into runner

    Move test's ownership connection into runner
    
    To ensure our integ test's tor instance is promptly terminated when the tests
    end we establish ownership over the process. As such we need to ensure our
    first controller connection lasts until we're all done.
    
    Moving this into the runner so our run_tests.py don't need to worry about it.
