/*
* 7/6/2020 - JH
* The deletion of the Workflow object graph is accomplished by a combination of SQL cascade deletes and
* PreSaveChanges() implementations.
*
* When a WorkflowType is deleted, any child Workflows will be cascade-deleted. Most children of the deleted
* Workflows will also be cascade-deleted, with the exception of any ConnectionRequestWorkflow records. Therefore,
* we need to manually delete those here in order to prevent foreign key violations within the database.
*
* Reason: GitHub Issue #4068
