[protege-owl] Minor SPARQL Bug

Hi,

In the category of things you shouldn't do but which I did anyway, you 
get a null pointer exception if you execute the following SPARQL query:

    SELECT ?entity WHERE { }

The direct cause is a need to test whether varNode is null after line 96 
of edu.stanford.smi.protegex.owl.model.query.SPARQLQueryResults.java 
(I'm using source from the SVN repository).
