[FrameworkBundle] Fixed variable name used in translation cache

This simply fixes the `$catalogueXXX` variable name used in the translation cache files in case the user use locales such as `en-US`, the generated variable's name was `$catalogueEn-Us`, with this fix it will be `$catalogueEnUs`.

This passes the config to ``getConfiguration`` instead of passing an empty array in ConfigurableExtension. This makes the class usable for bundle overwriting the ``getConfiguration`` method to use the config instead of using the default logic (which does not need the config).

[DI] Fixed bug requesting non existing service from dumped frozen container

[DI] Fixed bug requesting non existing service from dumped frozen container

When dumping a frozen container without aliases, the method `Container::has()` will throw a *"Warning: array_key_exists() expects parameter 2 to be array, null given"* warning. It's because `PhpDumper::addAliases` returns `''` if no aliases are given. This will work for a normal constructor, because it calls the `Container::__construct` method, but the frozen constructor doesn't do that. So it requires a `$this->aliases = array();` in the constructor.

This PR fixes this bug (and adds the test). Bug is introduced in #8252 and 63367a3d5615ff65251ccee4f73223107275f65f
