OnMessage is not fired when using XMPPClient with UCCX and XMPP.

I noticed no events were getting fired when listening to Cisco UCCX Event Notification Service (PUBSUB). After downloading this repo and opening the files manually and stepping through the code it seems line 1486 of Xmpplm.cs is only checking to see if the XMLNODE has a BODY tag, but messages from Cisco do not have a BODY, they have an EVENT tag.
