title: cucumber tests Fail with ActionDispatch::Cookies::CookieOverflow after rails4 upgrade
body: <p>The error looks like below.</p>
  
  <p>And I have already imported all books</p>
  
  <pre><code>#features/step_definitions/book_steps.rb:10
  ActionDispatch::Cookies::CookieOverflow (ActionDispatch::Cookies::CookieOverflow)
  features/reports/reports.feature:11:in `And I have already imported all books'
  </code></pre>
  
  <p>I searched around and decided to use the suggestions made in the following two posts, to switch to db session store.</p>
  
  <p><a href="https://stackoverflow.com/questions/9473808/cookie-overflow-in-rails-application">Cookie overflow in rails application?</a>
  <a href="https://stackoverflow.com/questions/17655744/rails-4-0-rake-dbsessionscreate">rails 4.0, rake db:sessions:create</a></p>
  
  <p>However, I still see this error in the cucumber tests.</p>
