Nowhere in the documentation do we mention that ObjectManager is
required for this API and frankly I don't think it's necessary, since
you only register one LEAdvertisement1 object at a time (whose path
you provide to RegisterAdvertisement already). ObjectManager was
necessary for the GATT API, since we needed to atomically fetch the
object paths and properties of an entire
Service/Characteristic/Descriptor tree, but in the LEAdvertisement1
case it's much simpler.
