Omit turbolinks configuration completely on skip_javascript generator option

before this commit, when you generate new rails app with `--skip-javascript` option `turbolinks` gem is removed from Gemfile(<a href="https://github.com/rails/rails/blob/55193e449a377c448e43d8fec42899ea1ff93b27/railties/lib/rails/generators/app_base.rb#L236">see app_base.rb</a>) but in `data-turbolinks-track` configuration options are always present in generated application layout.

I've installed rails/railties manually and tried to verify formatting:

    rails new demoapp --skip-bundle . ; cat demoapp/app/views/layouts/application.html.erb
    <!DOCTYPE html><html>
    <head>
      <title>DemoApp</title>
      <%= stylesheet_link_tag    "application", media: "all", "data-turbolinks-track" => true %>
      <%= javascript_include_tag "application", "data-turbolinks-track" => true %>
      <%= csrf_meta_tags %>
    </head>
    <body>
    
    <%= yield %>
    
    </body>
    </html>

which seems to be ok.
