Subject: [PATCH BlueZ] profiles/battery: Always update initial battery value

Due to cache in gatt db, bluetoothd fails to update publish the battery
value after reconnection when the battery value does not change compared
to before reconnection. For initial battery value, we should update the
value to D-Bus regardless of the cache value.
