Pathbuilder do not recognise a inverseOf a union in ranges and domains

Problem/Motivation

If the ontology has property ranges and domains, which use unions, pathbuilder can not reason properly the inverses of these properties.

Steps to reproduce

Import https://github.com/ISE-FIZKarlsruhe/nfdicore/blob/main/nfdicore.ttl to your triple store.
Try the path ... it works and shows you Organization, Consortium, Person, but if you try ... the path is broken.

Proposed resolution

Implement union lists for inverses.
