Bug 2021 - Continuous WARN log nodeConnector creation failed at node: OF|00:00:xx:xx:xx:xx:xx:xx

This fixes the bug in ToSalConversionsUtils.actionFrom() that mistakenly
passed an AD-SAL-style NodeID to a conversion utility (fromNodeConnectorRef)
that was expecting a MD-SAL-style NodeID.

Patch 8: Add unit test to exercise code path that exposes the issue
