WorkflowContextAware actions are generating hippo:log entries

With REPO-1861 the interface WorkflowContextAware was introduced with some methods. These methods can be invoked from client code, but since they are not annotated with 

@WorkflowAction(loggable = false, mutates = false)

they generate workflow action events in the hippo:log. Subsequently they show up in the dashboard with warnings (because there is no translation for them).
