x-has-more incorrectly set on CodegenOperation allParams

[samuelhewitt]

When using allParams, if there is a single bodyParam alongside other parameters, the vendorExtension x-has-more is overwritten with false. Most often, this ends up in missing commas in the generated files.

This is due to the bodyParam (and formParam) not being set as a copy in the various lists, instead the lists point to the same object.

An example test case is adding a put with body and path param to petstore-with-fake-endpoints-models-for-testing.yaml taken from the swagger-codegen project.

  '/pet/{petId}':
    put:
      tags:
        - pet
      summary: Updates a pet in the store with form data
      description: ''
      operationId: updatePetWithBody
      consumes:
        - application/json
      produces:
        - application/json
      parameters:
        - name: petId
          in: path
          description: ID of pet that needs to be updated
          required: true
          type: integer
          format: int64
        - name: body
          in: body
          description: Pet to update
          required: true
          schema:
            $ref: '#/definitions/Pet'
      responses:
        '405':
          description: Invalid input
