    filechooser: Remove outdated hack
    
    In GTK2, the filechooser was using a Paned, so switching between sidebar
    and files list with the arrow keys didn't work (the slider would be
    selected instead). So in
    https://bugzilla.gnome.org/show_bug.cgi?id=161489 a crude hack was added
    to make this possible.
    
    Over the years the filechooser code has changed so that it now would do
    this by default, yet the hack had been retained.
