netmiko: use netmiko-develop to see if IOXR doesnt detect None

ios and ios_xe are identical in Netmiko…so autodetect will use the more general ios selection.

I think the IOS-XR issue is likely fixed in the Netmiko develop branch (if you want to test that).

Just re-open if there is still an issue here.
