QNetworkConfigurationManager::allConfigurations returns many configurations.

Some of those are reported by the ipconfig tool as "media disconnected"
Additonally, some of them are hidden by the ipconfig tool and not reported at all.

In both cases, trying to open a connection using this configuration will time out (QNetworkAccessManager does not receive any signal from QNetworkSession).

Same usage works correctly on Symbian OS - the session fails quickly and emits the signal to indicate this.

New test case in tst_qnetworkproxyfactory, inNetworkAccessManager, takes a long time to run on windows because of this.
