Title: added failing validation tests

For some reason `.validate` is not working after I run `.build`. Am I using `.validate` wrong?

[This page](https://github.com/sequelize/sequelize/wiki/API-Reference-Instance#validate) says that it should return a promise with the error if the validation does not pass.
