displayLiteralPropertyValue helper changes value "0" to empty string

[kkda]

Maybe check for null or for datatype there.

This is the same for querylist helper

Generally Erfurt seams to rewrite "0" to empty strings when you da a sparqlQuery. So this should be an Erfurt issue.

Output of literal helper works fine with this change:

So please commit this change and close this issue. Maybe the sparql query bug and this one has a different cause.
