    Separate ParDoTest cases and make them more flexible
    
    A number of excessively rigid name tests preclude runner expansion
    of ParDo. This change makes them into independent unit tests
    for better signal and makes them more accurate to the intent - the
    name should have the relevant information, but may have other
    content.
