**TL;DR**
Fixes a fatal error when using `$this->kernel` in overridden `Client::setServerParameters` method happening since @Tobion commit https://github.com/symfony/symfony/commit/111ac18232dd660a3d23d9d0f1935aa914ffc43c.

**Long story**

In my tests, I'm overriding the `test.client.class` parameter to use a custom class which overrides the `setServerParameters` method with the following code :

```
    public function setServerParameters(array $server)
    {
        if (!isset($server['HTTP_HOST'])) {
            $server['HTTP_HOST'] = $this->getContainer()->getParameter('website_domain');
        }

        parent::setServerParameters($server);
    }
```

The purpose is to set the HTTP_HOST variable on every client request in the tests with the application domain (instead of the default value "localhost"). This fixed issues when switching between domains (standard, secure, etc) and also issues with CSRF protection.

If you know of a better idea on how to set this attribute with a value from a DIC parameter to every client request done in any tests in one place without overriding Symfony stuff, I'd be **very glad** to hear it. :)

**Detailed error**

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.
