Also add a unit test that exposes the problem.
Without these changes AMQP serialization fails with the following:
```
net.corda.serialization.internal.amqp.AMQPNotSerializableException: Constructor parameter - "reason" - doesn't refer to a property of "class net.corda.node.services.statemachine.SessionRejectException"

```
This is a split-out change from an enterprise feature, but since we do have: `RPCApi.RPC_TARGET_LEGAL_IDENTITY` header constant even in OS, it would make sense to extend RPC client API to populate this.
