KaleoInstanceLocalServiceImpl.updateKaleoInstance(long, Map, ServiceContext) does not persist KaleoInstance when changing workflow context

When changing the workflow context of a workflow instance by calling WorkflowInstanceManagerUtil.updateWorkflowContext() (forwarding to Kaleo implementation of WorkflowInstanceManager), the workflow context is changed in the workflow instance returned by the method, but the change is not committed to the database.

KaleoInstanceLocalServiceImpl.updateKaleoInstance() should call KaleoInstancePersistence.update() after changing the workflow context.

Untested correction is the following (note kaleoInstancePersistence.update()):

public KaleoInstance updateKaleoInstance(
		long kaleoInstanceId, Map<String, Serializable> workflowContext,
		ServiceContext serviceContext)
	throws PortalException, SystemException {

	KaleoInstance kaleoInstance = kaleoInstancePersistence.findByPrimaryKey(
		kaleoInstanceId);

	kaleoInstance.setWorkflowContext(
		WorkflowContextUtil.convert(workflowContext));

	kaleoInstancePersistence.update(kaleoInstance, false);

	return kaleoInstance;
}

The JBPM implementation correctly calls jbpmContext.save(token) in WorkflowInstanceManagerImpl.updateWorkflowContext().
