in secure mode, don't append the port to the Host header

because both calc_cn_host in cpprestsdk/Release/src/http/client/http_client_asio.cpp
and winhttp_client::send_request in cpprestsdk/Release/src/http/client/http_client_winhttp.cpp
compare the entire Host header value with the certificate Common Name
which causes an SSL handshake error
