Chaning RouterInterface => UrlGeneratorInterface

Further up on the page it's advised to use `UrlGeneratorInterface` as typehint. I don't know what the difference is, but I'm guessing that it saves you from `use RouterInterface` (if you need the `UrlGeneratorInterface` for something else anyway, as in this example). Is this right?
