[gtk/matthiasc/for-master: 16/16] modelbutton: Unify activation code paths

[Matthias Clasen <matthiasc src gnome org>]

commit 236fc57329f74573da10f4dfd97e99c9e2b8ec0d

    modelbutton: Unify activation code paths
    
    Opening submenus by Enter or Space wasn't working,
    because we had different code paths for activation
    via keynav and via click. Unify them.
