Title: missing dependency to can/model

in my case this missing dependency is causing that model instances, unless "'can/model'" explicitly stealed before validations.js, do not have validations

i see you have this comment in attibutes.js
```javascript
// in some cases model might not be defined quite yet.
if(clss === undefined){
return;
}
```

but was there a reason for not including dependency to can/model instead of that comment?
