relates to #148

[skodapetr]

Query looks invalid to me as ?p is not specified. However UV should rather show error about bad query then NullPointerException.

[mvi-eea-sk]

unable to simulate, probably was fixed in previous commits. Now it correctly shows Error:
"Query validator Query is not valid: QName 'skos:prefLabel' uses an undefined prefix"
