    status/network: Compare icon name to NULL instead of empty string
    
    Since the last commit we set the gicon property of StIcon to NULL if an
    empty string was given when setting the icon name, this means
    `st_icon_get_icon_name()` will return NULL instead of an empty string.
    
    When `getIndicatorIcon()` returns an empty string, the icon_name
    property will now be set to NULL, so compare it to NULL here.
