Workflows; Workflow Item's Last Updated date not available correctly from business layer

The finWorkflowItem.UpdatedUtcDate and UpdatedDate properties are not populated correctly and therefore, the 'Last Actioned' Workflow Item was not being highlighted correctly on the Workflow Summary Page; the first item was always highlighted instead.

NOTE: The 'Updated' properties are auditing properties and are not necessarily available in real-time; only when a Workflow object is reloaded from the database.

Also, the Workflow Item's UpdatedUtcDate property is now saved at full precision rather than rounded to the nearest hundredth of a second like most other date/ time values.
