    xmlParseNodeInContext problems with an empty document
    
    When you call xmlParseNodeInContext on a fragment node with an
    empty document, the parser associates the first new node twice --
    once with the document, and once with the fragment node.
    
    This fixes the issue by only associating the new node with the
    fragment node.
