placessidebar: show persistent drives when not showing Other Locations
Previous commits changes the behavior of GtkPlacesSidebar, as it stops handling persistent devices and only manages mounted networks, XDG directories and bookmarks. By radically breaking the previous behavior, we may have trouble since we provide no alternatives to that besides the private widget GtkPlacesView. Fix that by showing the persistent devices when not showing Other Locations item.
