Fix BatteryIcon reconfigure issue

The BatteryIcon widget's icon changes size if the widget is
reconfigured (e.g. via `cmd_reconfigure_screens`). This is because
the icon size is adjusted by the value of `image_padding`. This is
zero when the widget is initialised but has a larger value when the
widget is reconfigured.
