This reverts commit ec8aa158 partially in order
to reenable:
- delivery_causality_interaction_workflow
- delivery_movement_causality_interaction_workflow
- simulation_movement_causality_interaction_workflow

These interaction workflows do not generate activities directly, and do work
that can't be postponed.

By contrast, 'calculate' transition of delivery_causality_workflow is modified
so that no 'updateCausalityState' activity is created by default.
