### Environment

* Dubbo version: 2.7.5-SNAPSHOT
* Operating System version: macos
* Java version: 1.8.0_131

### Steps to reproduce this issue

We could run the following UT, then we could find the issue:

```
        ApplicationConfig application = new ApplicationConfig("provider");

        ServiceConfig<DemoService> service = new ServiceConfig<DemoService>();
        service.setProtocol(new ProtocolConfig("dubbo", 20880));
        service.setRegistry(new RegistryConfig(RegistryConfig.NO_AVAILABLE));
        service.setInterface(DemoService.class);
        service.setRef(new DemoServiceImpl());

        ConsumerConfig consumer = new ConsumerConfig();
        consumer.setLazy(true);

        ReferenceConfig<DemoService> reference = new ReferenceConfig<DemoService>();
        reference.setConsumer(consumer);
        reference.setRegistry(new RegistryConfig(RegistryConfig.NO_AVAILABLE));
        reference.setInterface(DemoService.class);
        reference.setUrl("dubbo://" + NetUtils.getLocalHost() + ":20880?" + DemoService.class.getName());

        DubboBootstrap bootstrap = DubboBootstrap.getInstance()
            .application(application)
            .service(service)
            .reference(reference)
            .start();

        Assert.assertEquals("true", reference.toUrls().get(0).getParameter("lazy"));
```

### Expected Result

Expected "lazy" : true

### Actual Result

Actual "lazy": false
