Fix Darwin framework operational advertising for new fabrics.

[bzbarsky-apple]

Bringing up a new fabric for the very first time was not correctly starting operational advertising for that fabric, because we were not propagating that state to the actual CHIPDeviceController. It happened to work for existing fabrics, because bringing up the controller factory starts operational advertising for fabrics that are already known at that point.
