fatal error during cache:clear when manually uninstalling an extension

[fritzmg]

Tested with the contao/managed-edition 4.4.1.

Reproduction

1. Manually install a Contao 3 extension that is compatible with Contao 4 by copying the extension folder to /system/modules.
2. Clear the cache.
3. Run the Install Tool.
4. Delete the extension folder from /system/modules again to uninstall the extension.
5. Run vendor/bin/contao-console cache:warmup or … cache:clear --no-warmup or … cache:clear. The following fatal error will occur:

PHP Fatal error:  Uncaught LogicException: The module folder "system/modules/news_sorted" does not exist. in …\vendor\contao\core-bundle\src\HttpKernel\Bundle\ContaoModuleBundle.php:36

The only way to uninstall such an extension is by deleting the extension folder and then deleting var/cache/prod manually.

This is a manager-bundle issue not core-bundle. No idea how to fix though 😔

Hm, true, in the standard-edition it would not happen, because you would have to manually remove it from the AppKernel anyway.

The issue has been moved to contao/manager-bundle#42.
