"file_locator" service or alias has been removed

[fritzmg]

In the constructor of the ContainerUtil you are retrieving a lot of services from the Symfony Container:

contao-utils-bundle/src/Container/ContainerUtil.php

Lines 36 to 42 in 153bf15

	public function __construct(ContainerInterface $container)
	{
	$this->framework = $container->get('contao.framework');
	$this->fileLocator = $container->get('file_locator');
	$this->scopeMatcher = $container->get('contao.routing.scope_matcher');
	$this->container = $container;
	}

This will not work in the most recent Symfony versions however, since some of these services are not public. It will lead to the following error for example:

[Symfony\Component\DependencyInjection\Exception\ServiceNotFoundException]
    The "file_locator" service or alias has been removed or inlined when the container was compiled. You should either make it public, or stop using the container directly and use dependency injection instead.

Instead of getting the services from the container, you need to use dependency injection.
