This reverts commit 393c652.
This commit was supposed to fix a bug but it add more failures.
If you wish, I can find out why 3.2 branch does not work with the patch, since I've wrote this fix for the master – https://github.com/rails/rails/blob/master/actionpack/lib/action_dispatch/middleware/session/abstract_store.rb#L84.
@brainopia if you can please do it.
@rafaelfranca done, #7316
