[gnome-dictionary] app: Implement GApplication::activate

[Emmanuele Bassi <ebassi src gnome org>]

    app: Implement GApplication::activate
    
    If we launch the Dictionary via DBus activation, we'll get an error
    because we don't implement/override the activate signal.
    
    There was a stub which tricked `git grep`, but gnome-continuous found
    the issue.
