[gtk+/gtk-2-24] Fix signal parameters in GtkEntryCompletion

[Federico Mena Quintero <federico src gnome org>]

commit 2479f13a07749172e39843cb51316c39d91f6ef3
Author: Matthias Clasen <mclasen redhat com>
Date:   Fri May 21 23:50:46 2010 -0400

    Fix signal parameters in GtkEntryCompletion
    
    The ::match-selected and ::cursor-on-match signal were emitted
    with the internal filter model instead of the user-provided model.
    
    Fixes bug #555087.
