[evolution] Remove e_tree_root_node_is_visible().

[Matthew Barnes <mbarnes src gnome org>]

commit 2965f986dd94257d4561472762803ec4ca671cda
Author: Matthew Barnes <mbarnes redhat com>
Date:   Thu Jun 20 11:17:40 2013 -0400

    Remove e_tree_root_node_is_visible().
    
    Reducing API bloat.  Do this instead:
    
      adapter = e_tree_get_table_adapter (tree);
      visible = e_tree_table_adapter_root_node_is_visible (adapter);
