Reduce queries in uniqueness validation

Reported by Carlos Júnior (xjunior) | October 28th, 2008 @ 02:11 PM | in 3.x

When you're doing a uniqueness validation, you don't have to do it if the value haven't changed. Even if it's nil, because the validation should be done by the presence validation.
