ObjectProperty and AnnotationProperty nodes should have Property label

[David Osumi-Sutherland]

[Nico Matentzoglu]

Check this, I think this is fixed. The way this works is like this:

By default, the importer will generate a Property label for all Data, Object and Annotation properties. So you dont need to do anything to get that. This behavior can be overwritten with add_property_label = false in the config file.
