Description

My PC has 2 network adapters and if I don't disable one one of them, I see:
```019-01-18 11:28:26,447 WARNING lbrynet.extras.daemon.Components:651: upnp discovery failed: failed to get lan and gateway addresses: 2
2019-01-18 11:28:26,447 WARNING lbrynet.extras.daemon.Components:665: unable to get external ip from UPnP, checking lbry.io fallback```

Research direction

Start by reproducing the UPnP discovery failure with two enabled network adapters and trace the path around the logged “failed to get lan and gateway addresses” warning in lbrynet.extras.daemon.Components. Check how the discovery result is handled, then verify that UPnP discovery either succeeds or reports the multiple-adapter case appropriately.
