Don't display foreign label variants if they are shown using a more specific property

[osma]

At which URL did you encounter the problem?

http://finto.fi/cn/en/page/3199A

What steps will reproduce the problem?

1. Open above URL (CN: A. Ahlström (yhtiö). Euran paperi)
2. Look at the "IN OTHER LANGUAGES" field

What is the expected output? What do you see instead?

The name variants "Euran paperi" and "Ahlström. Euran paperi" are duplicated also in the variant name field.

Skosmos should notice that the RDA property for variant names is a subproperty of skos:altLabel (based on a rdfs:subPropertyOf triple in the CN data) and that the two variant names are also expressed using the more specific RDA property. Thus Skosmos should not display them in the "IN OTHER LANGUAGES" field and since there are no other values there, the whole field should not be shown.

In practice, this involves changes mainly to the Concept.getForeignLabels method.

This leaves open the issue of having values in other languages, i.e., how would you implement it in the case there are values in the subproperties of other languages? They will not be shown on the subproperty field in any case.
And secondly, what if there are more values in the skos:altLabel than for the subproperty one? Should one show the both, then?

Also, I just noticed that those values are listed there only because they have no language tag and, thus, are in "foreign" language (otherwise they would be in the ENTRY TERMS section). This complicates the issue even further.

I'd do it like this in Concept.getForeignLabels:

• Take the list of all the altLabel values for the current concept
• Remove from the list all the values for which there exists a subproperty-of-altLabel triple with that value
• Return what remains in the list
