    Remove redundant arg check in nova-manage cell_v2 verify_instance

    argparse will validate that the --uuid is provided, we don't need
    an explicit manual check for that in the code, plus the manual
    check was violating the --quiet option by printing out an error
    message anyway.

    This also removes the unit test which we don't really need as
    argparse is going to do it's job.
