[evolution] Remove e_tree_node_is_expanded().

[Matthew Barnes <mbarnes src gnome org>]

commit 7742fe08606c4d491355e8add61083284ec1264f
Author: Matthew Barnes <mbarnes redhat com>
Date:   Thu Jun 20 10:14:30 2013 -0400

    Remove e_tree_node_is_expanded().
    
    Reducing API bloat.  Do this instead:
    
      adapter = e_tree_get_table_adapter (tree);
      expanded = e_tree_table_adapter_node_is_expanded (adapter, path);
