Use RouterInterface instead of Router in the listener

[Toflar]

Otherwise Contao 4.7 won't work due to ChainRouter being passed instead.

We might want to add more optimizations for Contao 4.7 because we're using Symfony CMF Routing now and we'll be able to add the routes dynamically instead of deleting and updating cache files but this is a quick fix to ensure compat I guess 😄

This is the exception (in case it helps):

Argument 1 passed to Terminal42\UrlRewriteBundle\EventListener\RewriteContainerListener::__construct() must be an instance of Symfony\Bundle\FrameworkBundle\Routing\Router, instance of Symfony\Cmf\Component\Routing\ChainRouter given, called in …/var/cache/prod/ContainerFDpN0DW/getTerminal42UrlRewrite_Listener_RewriteContainerService.php on line 11

Hey @leofeyer do you mind checking if 88d183a works for you? I would fix the unit tests afterwards.

Yes, it works. 👍
