  Log Message:
  -----------
  Remove "unresolved object ref" warnings (MID-5814)

Now we correctly use AuditHelper (model-impl) when auditing workflow
events.

Also:
1. added assertions on log entries collected from operation result,
2. fixed op. result handling in WorkflowEngine.executeRequest().
