Publish validation events when running as validator with reflector

[noursaidi]

These were not published because the reflect client was not a data sink for validation events:

private void sendValidationMessage(String deviceId, Object message, String topic) {
    try {
      String messageString = OBJECT_MAPPER.writeValueAsString(message);
      dataSinks.forEach(sink -> sink.publish(deviceId, topic, messageString));
    } catch (Exception e) {
      throw new RuntimeException("While sending validation event for " + deviceId, e);
    }
  }
