test(api-v2): Test an ontology with only one entity

[benjamingeer]

• Add minimal-onto.ttl and test how it's served in JSON-LD (always with @graph).
• When updating test response files in OntologyV2R2RSpec, don't update RDF/XML files if only their blank node IDs have changed (makes it easier to check the really changed files into git).
• Remove a generated client code file from git (this was causing confusing random errors in the client code test).

Resolves #1428.

Thanks! I will try that JSOn-LD in knora-api-lib-js.

I have added this in dasch-swiss/dsp-js-lib#28

So "@graph" is also an array if it contains just one element?

Yes, Knora always inserts @graph in an ontology response, and the JSON-LD processor will keep the @graph if there is something else at the top level (you can see this behaviour in the JSON-LD Playground). The JSON-LD processor moves the contents of @graph to the top level only if the graph contains one node and the document contains nothing else.

Thank you, you are a true minimalist!
