[empathy] Move the geoclue geocoding in EmpathyTpContactFactory

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

commit d13ba3658eded1649daff133cb04c76f6e3a906b
Author: Pierre-Luc Beaudoin <pierre-luc pierlux com>
Date:   Wed May 27 11:57:14 2009 -0400

    Move the geoclue geocoding in EmpathyTpContactFactory
    
    This code needs to be run when ever there is a new location available
    It makes more sens for it to be there. This makes the geolocation informtion
    ritcher as it can be displayed on a map.
