Inconsistent get responses 

The get response of ENDPOINT_TO_UNIVERSE uses a reference to the first field of the get request:
```
  "get_response": [
    { "$ref": "#/get_request/0" },
   ...
```

The get response of DMX_PERSONALITY_DESCRIPTION repeats the field:
```
  "get_response": [
    { "name": "personality", "type": "uint8" },
   ...
```

Whilst both are valid. What is the preferred approach?
