Incorrect HTTP method in response message and duplicate Link header when creating a container

curl -iX POST -H'Link: <http://www.w3.org/ns/ldp#BasicContainer>; rel="type"' https://example.org/

HTTP/2 415
link: <.acl>; rel="acl", <.meta>; rel="describedBy", <http://www.w3.org/ns/ldp#Container>; rel="type", <http://www.w3.org/ns/ldp#BasicContainer>; rel="type"

PUT request require a valid content type via the Content-Type header

Note POST request but PUT in response message.

curl -iX POST -H'Content-Type: text/turtle' -H'Link: <http://www.w3.org/ns/ldp#BasicContainer>; rel="type"' https://example.org/

HTTP/2 201
location: /c4db39a0-2bc3-11ea-b34b-d1f743b7eb53/
link: <.acl>; rel="acl", <.meta>; rel="describedBy", <http://www.w3.org/ns/ldp#Container>; rel="type", <http://www.w3.org/ns/ldp#BasicContainer>; rel="type", <http://www.w3.org/ns/ldp#BasicContainer>; rel="type"

Created

Note duplicate LDP-BC rel=type. Same as https://github.com/solid/node-solid-server/issues/426

先重現 issue 中的兩個 POST 請求，並追蹤 NodeJS 伺服器中的容器建立 HTTP 處理流程。確認錯誤訊息指明的是 POST 而不是 PUT，並確認回應在 Link 標頭中只發出一次 LDP BasicContainer 類型。
