docs: Internal method to remove requests. If request has not been passed to the
  {@link SpiceService} yet, all listeners are unregistered locally before
  being passed to the service. Otherwise, it will asynchronously ask to the
  {@link SpiceService} to remove the listeners of the request being
  processed.
  @param request
  Request for which listeners are to unregistered.
