Bluetooth Pairing: Sometimes PINs differ by leading zero

[DamageIncorporated]

This is an issue I encountered when helping to debug issue #49 in AsteroidOSSync

In a row of retries pairing phone and watch, both devices sometimes (not always) displayed slightly different PINs.
The phone displayed the same PIN as the watch, but with a leading Zero.

Example:
Phone: 065874
Watch: 65874
