    preferences: Set default_width to omit back button
    
    The sizing of the preferences window depends on the button labels and
    tends to be too narrow which makes the "back" button of
    `HdyPreferencesWindow` to be shown. It's a bit weird to see this on the
    desktop when there's plenty of space available.
    
    This is shown by `HdyHeaderBar` when it considers a window to be
    "mobile" which happens when its width is less than MOBILE_WINDOW_WIDTH
    (400) or it's height less than MOBILE_WINDOW_HEIGHT (800) (see
    `libhandy/src/hdy-header-bar.c`).
