Fix WebSocketClientHandshaker not generating correct handshake request when path is empty (#10095) 

Motivation:

WebSocketClientHandshaker#upgradeUrl doesn't comperly compute relative url when path is empty and produces url such as `?access_token=foo` instead of `/?access_token=foo`.

Modifications:

* fix WebSocketClientHandshaker#upgradeUrl
* add tests for urls without path, with and without query

Result:

WebSocketClientHandshaker properly connects to url without path.
