This happens because rack 1.3.0 still exists in your app's bundler cache and 
the stacks prior to cedar do not "bundle exec" when running your app. You could 
work around this by deleting and recreating the app. You could also give the 
cedar stack a try which does not have this issue.

Cheers,
David
