[Ruby] Loading concepts fails

[mkllnk]

Loading vocabularies fails with the old and new version of vocabularies. With the old version it shows an error in the parser:

connector-codegen/src/org/datafoodconsortium/connector/codegen/ruby/static/lib/datafoodconsortium/connector/skos_parser.rb

Lines 87 to 92 in 07ec67e

	def createSKOSConcept(element)
	skosConcept = DataFoodConsortium::Connector::SKOSConcept.new
	skosConcept.semanticId = element.id
	skosConcept.semanticType = element.type
	return skosConcept
	end

The parser tries to create a concept without giving it its mandatory semantic id.

I also tried the new files but encountered the same error as the current version of the ruby connector raises:

• Loading newest taxonomies fails connector-ruby#19

Hi @mkllnk can you try it using the issue3 branch of this repo with the codegen-issue3 branch of the data-model-uml repo?

Yes, that solves the issue. Can you merge?
