[empathy] Move the geocoding to when the location is updated

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

commit cc7656ce36f0a531cc21585de63d1c2e493bc993
Author: Pierre-Luc Beaudoin <pierre-luc pierlux com>
Date:   Tue May 26 16:52:48 2009 -0400

    Move the geocoding to when the location is updated
    
    This way, when the location is updated, the lat,lon is fetched too
    (not only upon showing the map).
