move has_emeter implementation from SmartDevice to SmartPlug, avoid using features() internally (#93)

* move has_emeter implementation from SmartDevice to SmartPlug, avoid using features() internally

* add stacklevel to deprecation warnings to see where they are really called

* make tests pass on a real device. if PLUG_IP is not None, the tests will be run on a device at the defined IP address
