Add a new-line to the end of route method generated code.

[arthurnn]

Fix regression on route method that was added by
bac812a. The regression was that when
calling the route method, we were not appending a \n anymore.

[fixes #19316]

This fixes the bug, but it still means that there is a slight (inconsequential?) difference in behavior from 4.2.0. The scaffold generator used to add an extra newline; now it does not.

4.2.0 after running rails g scaffold for user and post:

Rails.application.routes.draw do
  resources :users

  resources :posts

end

4.2.1:

Rails.application.routes.draw do
  resources :users
  resources :posts
end

Again, this is just a whitespace difference. No big deal? (I think I actually prefer the new behavior.)
