[empathy] Force an unset presence type to appear as offline in the presence chooser and status icon.

[Guillaume Desmottes <gdesmott src gnome org>]

commit 1020f57c4a8ea74b7738b6a8e20d299cdd65115d

    Force an unset presence type to appear as offline in the presence chooser and status icon.
    
    An unset presence type *does* make sense, but not in these
    contexts. As an aside, there is no icon for an unset presence, so
    nothing is displayed, which is bad.
    
    Fixes bug #597819
