[gnome-contacts/fix-unowned-warnings: 1/2] Declare all [GtkChild] members as unowned

[Niels De Graef <nielsdg src gnome org>]

commit 53bee039a27b51c283ee1b3022f047faf287ba7f
Author: Niels De Graef <nielsdegraef gmail com>
Date:   Sat Feb 13 11:07:41 2021 +0100

    Declare all [GtkChild] members as unowned
    
    These members are already owned by their respective parent widgets, so
    you shouldn't keep an extra reference on them. Vala also warns about
    this in the latest version, so this fixes quite a few warnings on
    the latest `valac`.
