Updated composer constraints for #6058

This is the implementation of #6058 

I've updated `composer.json` **and** ran composer to update `composer.lock`. Here are the dependencies that were updated:

- Updating twig/twig (v1.16.0 -> v1.16.1)
- Updating symfony/console (v2.5.4 -> v2.5.5)
- Updating tedivm/jshrink (v0.5.1 => v0.5.2)
