When creating child route, CLI adds /...

v1 beta 5

The deprecated router uses `/...` to denote a child router. The CLI is not using the deprecated router. Yet when I create a route and a child route, I get this. There should not be a `/...`

```
  {path: '/foo/...', component: FooComponent}
```

to reproduce:

```
ng new myapp 
ng g r foo
ng g r foo/bar
```
