Fix that Graphryder cannot understand multilingual code names provided by Open Ethnographer

[tanius]

Due to a recent feature addition to Open Ethnographer, ethnographic codes can now have multiple names, each with a language code assigned. The multiple names are also provided via API. A code record in JSON format obtained via API could be as follows, for example:

{
    "id": 1234,
    "description": null,
    "creator_id": 123,
    "created_at": "…",
    "updated_at": "…",
    "ancestry": null,
    "names": [
        {"name": "Internet generation", "locale": "en"},
        {"name": "Internet-Generation", "locale": "de"}
    ]
}

This has already been fixed by @aerugo in the version running behind graphryder2.edgeryders.eu, but the changes are yet to be provided upstream. Also, the current solution has to be refactored somewhat before including it here. This issue is a reminder for that 🙂
