TASK: Extends exception message with NodeType name

[markusguenther]

When the NodeType property name is not available for the given NodeType we throw an exception. The exception method only mentions the property name, and that can be irritating when you have multiple NodeTypes with that property name or multiple errors. So this change extends the error message with the current NodeType name.
