    application: Instantiate ShellSearchProvider only when registering
    
    Now that the --version flag was implemented using the
    handle_local_options virtual method, it is possible that the
    Application may exit without ever touching D-Bus. So it is a tad
    wasteful to instantiate the ShellSearchProvider when it is never going
    to be used. Since we are unreffing it in dbus_register, we might as
    well create it in dbus_register.
