    """Handle logic of disabling json templating engine and setting HTTP code.
    We return 204 on delete without content. However, pecan defaults empty
    responses with the json template engine to \null\, which is not empty
    content. This breaks connection re-use for some clients due to the
    inconsistency. So we need to detect when there is no response and
    disable the json templating engine.
    See https://github.com/pecan/pecan/issues/72
