title: skip_after_action rails version
body: <p>I´m using rails 4.3 and when I´m using the fonction skip_after_action I got an error:</p>
  
  <p>undefined method `skip_after_action' for #UsersController:0x007f5c7ebb6ea8</p>
  
  <p>I´ve try to found if maybe this function isnt in this version of rails but I´ve found nothing.</p>
  
  <p>Maybe someone can help me!</p>
  
  <p>My controller is this one</p>
  
  <pre><code>class UsersController &lt; ApplicationController
    def show
     if params[:support] == 'mobile'
       skip_after_action :intercom_rails_auto_include
       render layout: 'mobile'
     end
    end
  end
  </code></pre>
  
  <p>Thank you.</p>
