Re-enable all tests for windows platforms.

Also, explicitly connect to the IPV4 address.  On windows platforms supporting AF_INET6, the SocketProxy would connect using socket.create_connection('localhost', port) which would cycle through all address families and try to connect.  It would try connecting using AF_INET6 first and this would cause a delay of up to a second.
