      Unsubscribing a topic with QMqttClient and then directly subscribing it again, when using the QMqttSubscription classes returned by QMqttClient::subscribe.

      Example project attached.

      The slot onSubscription1 is never triggered
      The payload "trigger_subscription_1" is published correctly, as checked with "mosquitto_sub -h localhost -p 1883 -t Test".
