[BUG] generatedMapping.putIfAbsent is not generated

[welchi]

Describe the bug
The generated code does not include generatedMapping.putIfAbsent and an error occurs in the response.

To Reproduce
swagger:

openapi: 3.0.3

paths:
  /api/book/getList:
    get:
      responses:
        200:
          description: OK
          content:
            application/vnd.api+json:
              schema:
                title: GetBookListResponse
                allOf:
                  - $ref: "#/components/schemas/ApiResponse"
                  - properties:
                      book:
                        type: object
                        properties:
                          title:
                            type: string
components:
  schemas:
    ApiResponse:
      type: object
      required:
        - status
      properties:
        status:
          type: string
        error_message:
          type: string

generated code:

  ///
  Future<chopper.Response<GetBookListResponse>> apiBookGetListGet() {
    // comment: missing generatedMapping.putIfAbsent !
    return _apiBookGetListGet();
  }

  ///
  @Get(path: '/api/book/getList')
  Future<chopper.Response<GetBookListResponse>> _apiBookGetListGet();

Expected behavior
The generated code should contain a generatedMapping.putIfAbsent corresponding to the response type.

Library version used:
swagger_dart_code_generator: 2.13.5
or
master
