Title: Fixes issue with hasMany attributes beind set durring validation

Fixes issue with hasMany attributes beind set durring validation causing loaded to stay false instead of being set to true

Before:
```
e = new App.Event({ name: "Event 2"})
e.save()
e.get('event_templates.loaded') => false
e.get('event_templates.loaded') => false
```
After:
```
e = new App.Event({ name: "Event 2"})
e.save()
e.get('event_templates.loaded') => true
e.get('event_templates.loaded') => true
```
