Wrong label if multiple labels are provided

[marioscrock]

Describe the bug
A label with duplicated text is generated if both rdfs:label and skos:prefLabel are used. I assume the same error would happen if obo:IAO_0000118 is provided.

Expected behavior
I solved the issue by changing the extraction.xsl file and removing skos:prefLabel, however a better solution should be found to keep the or condition and do not add the duplicated text (select only one label if multiple labels are provided).

I think this is the first time I see someone having an issue due to too many annotations :)
You are correct, an OR is needed (or similar).
