[empathy] Copy GHashTable received from Dbus and refactor

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

commit 1d8091578b25a85b3d1d6d4c651a0c8e73c3fe2d
Author: Pierre-Luc Beaudoin <pierre-luc pierlux com>
Date:   Wed May 27 11:45:32 2009 -0400

    Copy GHashTable received from Dbus and refactor
    
    This makes the GHashTable's structure explicit and less error prone
    when inserting later on.
    
    Move the copied code over to a new function.
