QML debugging does not work if application uses proxy

Looks like binding of the socket is trying to make a request to proxy server. I am not sure if that is a feature, but it also prevents opening of the port for QML debugger if proxy server does not support it (do any?).

Startup of the application fails with following message:

QML Debugger: Unable to listen to port 54830.

To reproduce:

• set up a system proxy
• start debugging any QML application which uses the proxy and has QML debugger enabled
