desktop: Delay surface creation until committed

Some frameworks like GTK-3 delay the set_app_id until title and
parent are set, which makes ivi_check_pending_desktop_surface
unable to set the proper role on surface_added. A consequence
of this behaviour is that is not possible to use set_app_property
to configure an application as popup.

Instead, delay the creation of the surface until committed to give
the chance to have a valid app_id configured.
