  [presence_dialoginfo] Fix aggregating dialoginfo XML

Fix the looping when aggregating the dialog info XML documents with multiple dialog elements. The xmlUnlinkNode() function inside the loop is breaking the looping (the "next" member is reset).
Credits for reporting and fixing go to Damien Sandras (@dsandras)
Closes #2815
