Move setting $app['twig.app_variable'] after 'Symfony\Bridge\Twig' check

Currently `TwigServiceProvider ` sets `$app['twig.app_variable']` to be function that has a dependency on classes that are not required by Silex. This will fail if the user then calls that function. This happens for example when the [silex-pimple-dumper](https://github.com/Sorien/silex-pimple-dumper) maps over the app and tries to dump it's content.

This PR fixes that by moving this in the `class_exists('Symfony\Bridge\Twig\Extension\RoutingExtension')` check.

I've also added comment because at first it wasn't clear for me that this check for the `RoutingExtension` was the check for the whole Twig bridge. Please feel free to rebase and remove it it you don't like it or I misinterpreted it.

Keep up the good work! 👍

Specify relation of twig-bridge to symfony/config

When I install `symfony/twig-bridge` I've got `Class 'Symfony\Component\Config\Util\XmlUtils' not found in /vendor/symfony/translation/Loader/XliffFileLoader.php on line 53`

It's kinda related to comment https://github.com/symfony/symfony/issues/13194#issuecomment-90893304
