DMN Validator raising false positive errors for type resolution

DMN Validator is raising false positives for errors on type resolution. It looks like it is happening since the following commit was done:

https://github.com/kiegroup/drools/commit/9e2fdc4b5e83bb9b5350a37fd89dab8f38cc8582

The problem is that the .toString() call on the QName will return the full name, including the namespace:

{http://www.trisotech.com/definitions/_6cfe7d88-6741-45d1-968c-b61a597d0964}

And that will always fail the constraint:

ItemDefinition( name == $typeRef.toString() )

I believe the correct would be to change the constraint to:

ItemDefinition( name == $typeRef.getLocalPart() )

But we might also need to check the namespace somehow.
