[evolution] Remove e_tree_force_expanded_state().

[Matthew Barnes <mbarnes src gnome org>]

commit 662c1a21bf74ebb4724612eea840a3dd810860b4
Author: Matthew Barnes <mbarnes redhat com>
Date:   Thu Jun 20 12:10:02 2013 -0400

    Remove e_tree_force_expanded_state().
    
    Reducing API bloat.  Do this instead:
    
      adapter = e_tree_get_table_adapter (tree);
      e_tree_table_adapter_force_expanded_state (adapter, state);
