Url's port ignored when Apache HTTP Client is used

[sukolenvo]

Default http transport is Apache HTTP Client (link). But it doesn't support url port (ie. I can't use http://locahost:8080/ as BASE_URL_QBO in tests. Requests will be made to localhost:80).

I think root cause is that -1 is used as port in HttpTarget (source)
Is it possible to replace hardcoded value with url.getPort() (if port ommitted - it returns -1 anyway)? Happy to open PR.
