[nautilus/wip/gbsneto/other-locations] files-view: remove ::get_nautilus_window_slot method

[Georges Basile Stavracas Neto <gbsneto src gnome org>]

    files-view: remove ::get_nautilus_window_slot method
    
    NautilusFilesView manages its parent NautilusWindowSlot instance,
    but this is unecessary since Gtk+ already has parent management
    code.
    
    Clean up ::get_nautilus_window_slot code, and replace it by the
    Gtk+ equivalents.
