Serial in MovesenseResponse is different from in MovesenseDevice

[Steven Merel]

I'm subscribing to accelerometer data on a connected device. The value of MovesenseDevice.serial is ECKIB9CF76B7. When I get an accelerometer sample, the value of MovesenseResponse.serial is /ECKIB9CF76B (note the leading slash and missing final character.)
