Protocol and hostname are not parsed from url for HttpRequestImpl

[monrax]

The example that uses mock implementations in API.md results in an incomplete message that is ultimately dropped by the Resurface DB. This is due to the request_url field being skipped as both request.protocol and request.hostname are not present in the mock request instance.

How to reproduce?

// define request to log
const request = new HttpRequestImpl();
request.method = 'GET';
request.url = 'http://resurface.io';

// define response to log
const response = new HttpResponseImpl();
response.statusCode = 200;

// build JSON message
let msg = HttpMessage.build(request, response);

console.log(msg) // no request_url detail present in JSON

HttpMessage.send(logger, request, response); // this results in the request down below

//POST /message HTTP/1.1
//Content-Encoding: identity
//Content-Type: application/json; charset=UTF-8
//User-Agent: Resurface/2.2.1 (http_logger.js)
//Host: localhost:7701
//Connection: keep-alive
//Transfer-Encoding: chunked

//[["request_method","POST"],["response_code","200"],["now","1708555058014"],["host","MYPCNAME.local"]]

Parsing the given URL inside the HttpRequestImpl setter for the url field and setting protocol and hostname fields from there might help solve this issue.
