#70: HTTP Stubbing: URL matcher incorrectly strips port when using "ignore query parameters" option

[malcommac]

The following PR fixes the HTTPStubber with match(URL:) which specify both the host along with an explicit port. IN this case the host property of URL ignores the port returning only the host.
The result is a failure in matches() function which, incorrectly, return false.

This is an example:

let stub = HTTPStubRequest()
  match(URL: URL(string: "http://localhost:3001/some/path")!)
  .stub(for: .get) { _, _ in
    let response = HTTPStubResponse()
    response.statusCode = .ok
    return response
}
        
let matches = stub.matchers[0].matches(request: URLRequest(url: URL(string: "http://localhost:3001/some/path")!), for: stub)

In order to fix it we added a new a new fullHost property in URL which also consider the URL.
A test case is also added.
