Crash querying Google OnHub device: 'NoneType' object has no attribute 'findtext'

Hi there, I just tried probing my network then running the probe: I see this in the logs, and a server error over HTTP.

::ffff:192.168.86.31 - - [30/Nov/2019 16:08:57] "GET /probe?target=http%3A%2F%2F192.168.86.1%3A5000%2FrootDesc.xml HTTP/1.1" 500 59

Looks like it's looking for a deviceType urn:schemas-upnp-org:device:InternetGatewayDevice:1
, when the onHub ends with :2 instead of :1.

Assuming this is a dupe of #4
