Before this, we only exported the modem to DBus when all ports were organized, in order to make sure that we select as primary port the one we really want and not the first AT port grabbed. Given that to get all the ports organized we also needed to wait to get all the ports grabbed, we can now also defer the creation of the modem object until all the ports get grabbed. This allows us to create different types of objects based on the ports available (e.g. we can now create QMI-supported modem objects if we see a QMI port around).
