Expand updateOrderFulfillerStatus to also set accession number

The OrderService provides a service method "updateOrderFulfillerStatus" which is meant to work with the RESTful fulfiller details endpoint and allow a downstream fulfiller to update the fulfiller status and fulfiller comments.

The fulfiller could also want to set the accession number of the order, so we should expand this method to take this as a fourth parameter.

Note, for backwards compability we should keep the existing method signature and have it delegate to this new method.

This functionality should be backported to 2.3.x.
