    // Amqp requires that the resource designation NOT be terminated by a slash.  The agnostic twin client was terminating the
    // resources with a slash which worked just dandy for MQTT.
    //
    // We need to cut off a terminating slash.  If we cut off a terminating slash and the length of resource is zero then simply
    // don't specify a resource.
    //
    // What if the caller specifies a "//" resource?  Don't do that.
    //
    // So you'll note that in this case "/" sent down will be turned into an empty string.  So why not
    // simply send down "" to begin with?  Because you can't send a falsy parameter.
