docs: Disable request listeners notifications for a specific request.<br/>
  None of the listeners associated to this request will be called when
  request will finish.<br/>
  This method will ask (asynchronously) to the {@link SpiceService} to
  remove listeners if requests have already been sent to the
  {@link SpiceService} if the request has already been sent to the service.
  Otherwise, it will just remove listeners before passing the request to
  the {@link SpiceService}. Calling this method doesn't prevent request
  from being executed (and put in cache) but will remove request's
  listeners notification.
  @param request
  Request for which listeners are to unregistered.
