Title: Container::camelize also takes backslashes into consideration

I [complained](https://github.com/symfony/symfony/pull/8494) about unreported and unnoticed BC break.

Service names in our DI container contain backslashes and that pull request rendered newer versions of Symfony unusable for us.

This commit fixes this - it normalizes backslashes in service names into underscores.
