adapters/netbox: fix get_device for netboxv37 (#51)

NetboxStorageV37.get_device is broken in previous intration when I was adding fetching device neighbors.
It has not been noticed right aways since the most of the core logic is using more flexible make_devices API
which allows to fetch multiple devices at once.
