I'm unable to run the test from within TwigBundle

```bash
src/Symfony/Bundle/TwigBundle
composer install
phpunit
```
gives
```
PHP Fatal error:  Class 'Symfony\Bundle\FrameworkBundle\Templating\TemplateReference' not found
```

Adding the FrameworkBundle fixes this but is that what is needed?

I believe `require` and `require-dev` should use `dev-master`
- [x] require(-dev) is not up to par with symfony master.
