Revert "Merge pull request #16622 from matthewd/default-debug"

This reverts commit 2602a49a8600ab52f807599bbd5b1f9c0be4214f, reversing
changes made to 5d7c1057684c377bc2801c8851e99ff11ab23530.

The explicit default was introduced in 21f6d72, so apps created with Rails < 4
have the commented out version, which means that this change would break those
apps.
