correct bug on rawModel generation

[xavier-rodet]

When i used your fork, it generated my rawModels like that:

<?php


abstract class RawUser extends use Phalcon\Mvc\Model\Validator\Email as Email;
{
User
}

I just corrected it if you wanna merge !

Thanks Xavier! It looks like they made some changes in the official branch recently and I didn't notice that.
