Duplicate message descriptors generated for request schemas whose names end with "Request"

[TylerGillson]

Steps to reproduce:

1. Add the following to generator/testfiles/requestBodies.yaml:

/testRequestBodySchemaReference:
    post:
      operationId: testRequestBodySchemaReference
      requestBody:
        required: true
        content:
          application/json:
            schema:
              $ref: '#/components/schemas/TestRequestBodySchemaReferenceRequest'
      responses:
        "201":
          description: OK
components:
  schemas:
    TestRequestBodySchemaReferenceRequest:
      type: object
      properties:
        person:
          $ref: '#/components/schemas/Person'

2. Execute TestFileDescriptorGeneratorRequestBodies to generate an updated .proto file
3. Observe the following duplication:

message TestRequestBodySchemaReferenceRequest {
  Person person = 1;
}

message Person {
  int64 id = 1;

  int64 age = 2;

  string name = 3;

  repeated string photo_urls = 4;
}

//TestRequestBodySchemaReferenceParameters holds parameters to TestRequestBodySchemaReference
message TestRequestBodySchemaReferenceRequest {
  TestRequestBodySchemaReferenceRequest test_request_body_schema_reference_request = 1;
}

service Requestbodies {
  rpc TestRequestBody ( TestRequestBodyRequest ) returns ( google.protobuf.Empty ) {
    option (google.api.http) = { get:"/testRequestBody" body:"person"  };
  }

  rpc TestRequestBodyReference ( TestRequestBodyReferenceRequest ) returns ( google.protobuf.Empty ) {
    option (google.api.http) = { get:"/testRequestBodyReference" body:"person"  };
  }

  rpc TestRequestBodySchemaReference ( TestRequestBodySchemaReferenceRequest ) returns ( google.protobuf.Empty ) {
    option (google.api.http) = { post:"/testRequestBodySchemaReference" body:"test_request_body_schema_reference_request"  };
  }
}

I see. Thanks! Need to think about that a bit 🤔
