Duplicate "Client" struct generated if there is a component with the name "Client" in the openapi spec

[jedrivisser]

Tested this on latest and v1.11.0

Example of a minimal api that breaks code generation:

openapi: "3.0.0"
info:
  version: 1.0.0
  title: Client API
paths:
  /client:
    get:
      operationId: getClient
      responses:
        200:
          content:
            application/json:
              schema:
                $ref: "#/components/schemas/Client"
components:
  schemas:
    Client:
      type: object
      required:
        - name
      properties:
        name:
          type: string

config to generate code:

package: api
output: api/api.gen.go
generate:
  models: true
  client: true
