[empathy] Use the layer to list the markers

[Pierre-Luc Beaudoin <plbeaudoin src gnome org>]

commit a6727eb14a19681c1839e9aacf9abcb139ceb268
Author: Pierre-Luc Beaudoin <pierre-luc pierlux com>
Date:   Tue May 26 20:44:25 2009 -0400

    Use the layer to list the markers
    
    There was no need to add an extra list as the layer already has
    a list of the markers.
