rewrite order dependent test case. #8185

As reported (https://github.com/rails/rails/pull/8185#issuecomment-11702226)
this test relied on the order a hash was serialized. Comparing the parsed
hash makes the test no longer order dependent.
Fixed couple of typos

Revert "reminder to run bundle after setting up rails-dev-box"

This reverts commit 41381c19d1f3920ee9540aff0d35209cb43fb057.

someplace else if it's explicitly required.

Revert "Add rake default to description"

This reverts commit 0d8ca8124de9b3a5f6398a28d79baca935a1f96c.

Reason: docrails isn't the place to do this. Also, I feel this is
not really required.

We'll be taking a different tack on this with new `bundle binstubs <gem>` support.
work off FIXME comments in AR rename_column_test.rb

There were a couple of tests, which had FIXME comments in palce of
assertions. I replaced these FIXME comments with actual assertions to
