    Fixed fallout from GtkScrollable patches.
    
    The scrollable patch removed set_scroll_adjustments (NULL, NULL) from
    gtk_tree_view_init() which ensured the treeview would have adjustments
    at all times, this patch adds set_v/hadjustment (NULL) to _init to ensure
    the same thing (without it, there are crashes when trying to access the
    adjustments notably from set_headers_visible() in gedit).
