Implement ListDevicesByOwner. Write a unit test for listing Devices by their Owner property, as per our Storer interface. Basically, if we insert Devices into the datastore, we need to be able to retrieve the Devices that someone owns. Simple enough. This meant that I needed to implement the Memstore version, past the barebones stub, so the tests would continue to pass.
