Ignored validationKeywords for $ref types

[darren-demicoli-tma]

I have the following typescript definitions file test.ts:

interface AddressInfo {
  /**
   * @default xxx
   */
  address: string;
}

interface UserInfo {
  /**
   * @default xxx
   * @label xxx
   */
  name: string;
  /**
   * some desc ...
   *
   * @label xxx
   */
  extra: AddressInfo
}

I generated the schema using
typescript-json-schema test.ts UserInfo --out schema.json --validationKeywords label

and the generated schema is the following:

{
    "$schema": "http://json-schema.org/draft-07/schema#",
    "definitions": {
        "AddressInfo": {
            "properties": {
                "address": {
                    "default": "xxx",
                    "type": "string"
                }
            },
            "type": "object"
        }
    },
    "properties": {
        "extra": {
            "$ref": "#/definitions/AddressInfo",
            "description": "some desc ..."
        },
        "name": {
            "default": "xxx",
            "label": "xxx",
            "type": "string"
        }
    },
    "type": "object"
}

As can be seen, the extra property contains the $ref and the description but is missing the label annotation.
