Use a device's UUID instead of a random one when parsing inventory

SUMMARY

Currently, the inventory plugin randomly generates a UUID for all devices that don't have a name:

nautobot-ansible/plugins/inventory/inventory.py

Line 1211 in e4135d0

return host["name"] or str(uuid.uuid4())

Instead, I think we should use the device's UUID that we got back from Nautobot instead of using a randomly generated one.
