Delegate error to action dispatcher

Currently, it is not possible to catch an error thrown by a handler at the location where the action was dispatched when the error was thrown on the server.

The server does not delegate the error, it catches the error and sends a MessageAction:

Suggested solution:
Introduce ExecuteOperationRequestAction which wraps the operation and has a response on completion or throws error. This should then be orthogonal to existing code but allow the requested functionality.
