Title: is_changed('field') was always returning true

Broken here, by a seemingly unrelated commit.

https://github.com/fuel/orm/commit/df62d1115888a81bff822ae9a038d823b9a3fbc2

```is_changed('field')``` will always return ```true```.

For now I have just removed the code that was added, as it isn't clear what you were trying to achieve.
