Dirty Tracking (partial updates) don't see decimal column updates

The attached test looks flawed to me. It changes big_bank_balance, then checks to see whether world_population has changed. As you'd expect, it hasn't.

Altering the test to change big_bank_balance then test if the change has persisted doesn't fail. I don't believe this issue is valid any more.

Not Reproducible.

Fixed the original test based on Tom's findings and no failures are reported.

I've attached a patch.
