    Add more unittests for Bridge.updateFromExtraInfoDescriptor().
    
     * ADD test_Bridge_updateFromExtraInfoDescriptor_pt_changed_args() which
       checks that updateFromExtraInfoDescriptor() updates known PTs with
       their new args from a newer parsed extrainfo descriptor.
    
     * ADD test_Bridge_updateFromExtraInfoDescriptor_pt_died() that
       updateFromExtraInfoDescriptor() removes previously known PTs which
       are no longer listed in a Bridge's extrainfo descriptor.
