[ws server]: host-filtering with wildcard as port number doesn't work

[niklasad1]

Host-filtering with wildcard in the port field doesn't work.

	let server = WsServerBuilder::default()
		.set_allowed_hosts(["http://localhost:*", "http://127.0.0.1:*"])
		.unwrap()
		.build("127.0.0.1:0")
		.await
		.unwrap();

      	let client = WsClientBuilder::default().build(&server_url).await.unwrap();
	let client = Arc::new(client);

	let r = client.request::<String>("say_hello", None).await;
        
        // Fails with 403 because the entire address is compared such as as `http://localhost:31881 !=  http://localhost:*`
	assert!(r.is_ok());

I have checked the HTTP server and it actually supports wildcards.
