    The environment variable #{variable_name} is not set. If you are in test
    mode, make sure you set the correct vars in your helpers. If you get this
    error in development, make sure you run rails or rake with `govuk_setenv`
    and puppet is up to date. RABBITMQ_HOSTS, RABBITMQ_VHOST,
    RABBITMQ_USER and RABBITMQ_PASSWORD are deprecated. Please switch to
    RABBITMQ_URL.
