[Typescript-Angular2] Array items exported as extending "models.Array"

Description

If I define a model definition as just an array, then the created model ts file says "extends models.Array" instead of just "extends Array"

Swagger-codegen version 2.2.1

Swagger declaration file content or url

swagger: "2.0"

host: localhost
schemes:
  - http
consumes:
  - application/json
produces:
  - application/json
paths:
  /test:
    get:
      tags:
        - test
      operationId: test
      description: test
      responses:
        "200":
          description: Success
          schema:
            $ref: "#/definitions/TestArray"

definitions:
  TestArray:
    type: array
    items:
      $ref: "#/definitions/TestItem"

  TestItem:
    properties:
      val:
        type: string

The invalid generated model for TestArray is then:

export interface TestArray extends models.Array<models.TestItem> {

}

whereas it should just be as follows (without "models."):

export interface TestArray extends Array<models.TestItem> {

}

Command line used for generation

java -jar swagger-codegen-cli-2.2.1.jar generate -i ./swagger.yaml -l typescript-angular2 --additional-properties modelPropertyNaming=original

Suggest a Fix

For the time-being, I have my codegen run within a script that uses sed to replace the values after generation:
sed -i '' 's/extends models\.Array/extends Array/g' *

Start with the provided swagger.yaml definition and run the listed swagger-codegen-cli command using the typescript-angular2 generator. Inspect the generated TestArray model and the generator templates or entry points that produce its extends clause; done means array models extend Array without the models. prefix while item models remain correctly qualified.
