scan output should have type, not kind

[edaniszewski]

fixes a bug in the scan output found by @MatthewHink where the type field displayed the device kind, not the type.

added unit test, and did a test locally with a modified emulator -- you see that the scan reports the type as temperature, but the capabilities endpoint shows the full kind as test.temperature
