Signal received after workflow is closed

@tihomir Inspired from this post, do you think this may can help?

Currently, what we used is io.temporal.workflow.Workflow.continueAsNew(args);

Changed to:

MyWorkflow next = io.temporal.workflow.Workflow.newContinueAsNewStub(MyWorkflow.class);
WorkflowStub.fromTyped(next).start(args);
