Changing a "First on bus" sensor in the device manager sends an incorrect address to the Arduino

[elcojacobs]

When a RevA shield is used, with sensors configured as 'first on bus', changing their settings in the device manager sends an incorrect address to the Arduino.

Device config command sent, U:{"i":"3","c":"1","b":"0","f":"5","h":"2","p":"22","a":"First on bus"}

This causes the sensor to be installed with address F2BCF87BFCFFFFFF.

The correct implementation would be to send address 0.
