Fix proxy when changing only the password 

QHttpThreadDelegate doesn't take into account the password to compute the
key of the networkconnection hash. So if only the password for a proxy has
changed, the wrong data gets used for the connection.

This patch simply adds proxy->password() to the key.

Here are the steps to reproduce the bug:
 * Use an authentified proxy and provide the correct username but a wrong
password

```
 QNetworkAccessManager networkAccessManager;
 QNetworkProxy proxy(QNetworkProxy::HttpProxy, PROXY_HOST, PROXY_PORT,
                     "goodusername", "badpassword");
 networkAccessManager.setProxy(proxy);
``

 * As expected, the reply returns ProxyAuthenticationRequiredError

 * Using the same QNetworkAccessManager, setup a new proxy with the
correct credential:

```
 QNetworkProxy proxy(QNetworkProxy::HttpProxy, PROXY_HOST, PROXY_PORT,
                     "goodusername", "goodpassword");
 networkAccessManager.setProxy(proxy);
```

 * The reply still returns ProxyAuthenticationRequiredError

[ChangeLog][QtNetwork] Fix proxy-authentication issue, after a wrong password
has been used, when supplying the right password.
