Unstructured event add not handled

Add events on Unstructured CustomResources gets CreationTimestamp set to default Value as it's missing the 

case *unstructured.Unstructured:
		objectMeta = meta_v1.ObjectMeta{
			CreationTimestamp: object.GetCreationTimestamp(),
			Namespace: object.GetNamespace(),
		}
	}

in GetObjectMetaData,

which results in events being skipped as creationTimestamp will always be < serverStartTime
