CORDA-1645: Checkpoint before calling an idempotent sub-flow. (#3399)
* CORDA-1645: Checkpoint before calling an idempotent sub-flow. When an idempotent sub-flow causes a flow restart, the flow will be replayed from the last checkpoint before the sub-flow invocation. However, the logic between the last checkpoint and the sub-flow invocation may contain side-effects which shouldn't be replayed. Thus we need to persist a checkpoint just before an idempotent sub-flow is invoked.
