Unexpected message arrived for topics without leading /

[sgofferj]

When using a topic prefix without a leading "/", e.g. "IoTmanager" instead of "/IoTmanager", nothing happens on the dashboard and the log shows "Unexpected message arrived".

It is allowed to use a leading forward slash in MQTT, for example /myhome/groundfloor/livingroom. But that introduces a unnecessary topic level with a zero character at the front. That should be avoided, because it doesn’t provide any benefit and often leads to confusion. (http://www.hivemq.com/blog/mqtt-essentials-part-5-mqtt-topics-best-practices)
