Improve FaceManager test suite with coverage for these functions and situations:

• faces/create command with malformed FaceUri DONE
• faces/create command with non-canonical FaceUri DONE
• faces/create command with a FaceUri of unsupported scheme DONE
• face query operation with LocalUri condition
• face query operation with RemoteUri condition
• face query operation with FacePersistency condition
• face query operation with LinkType condition

Additionally, the test suite should manage a NetworkMonitor instance, and stop using deprecated FaceSystem(FaceTable& faceTable) constructor before deleting that constructor. DONE
