should_require_attributes doesn't play nice with validate callback

[Andy Ferra]

I know there have been similar post about this but as far as I've
reviewed the points they cover (I think) and it's still not working.

Things I can say about the code:
- validates_presence_of is being declared correctly
- valid? returns true
- a record for the tests to hit is being create (via Factory)
- IF I change validate it validate_on_create the test passes BUT,
fails when set to validate_on_update

Here's the code:

Ok, I just had a modified the validation method so it doesn't throw
errors when the values aren't set.

But, I still don't understand why the test fails because the record
isn't empty.

Anyone care to explain?
