[balsa] Use gtk_scrolled_window_get_{h,v}adjustment()

[Peter Bloomfield <peterb src gnome org>]

commit 99ff4602807f4447634746cfdaa6913cb00060f3
Author: Peter Bloomfield <PeterBloomfield bellsouth net>
Date:   Thu Jul 5 17:32:58 2018 -0400

      Use gtk_scrolled_window_get_{h,v}adjustment()
    
    * src/balsa-message.c (bm_find_scroll_to_rectangle), (select_part):
      Use gtk_scrolled_window_get_{h,v}adjustment() instead of
      GObject properties (and consequently, do not leak the
      adjustments).
