Symfony version(s) affected: 4.3.4

Description
In Symfony 4.2 the logger service could be injected by type. After upgrading to 4.3.4 I can only inject it by using the argument name.

How to reproduce

// MyClass.php

namespace App\MyNamespace;

use Psr\Log\LoggerInterface;

class MyClass
{
    /**
     * @var LoggerInterface
     */
    private $logger;

    public function __construct(LoggerInterface $logger)
    {
        $this->logger = $logger;
    }
}

# services.yaml

services:

    App\MyNamespace\MyClass:
        arguments:
            Psr\Log\LoggerInterface: '@monolog.logger.my_channel'

In Symfony 4.3.4 I get the following error message:

In ResolveNamedArgumentsPass.php line 57:
Invalid service "App\MyNamespace\MyClass": did you forget to add the "$" prefix to argument "Psr\Log\LoggerInterface"?

It can be fixed by using a the argument name in services.yaml:

# services.yaml

services:

    App\MyNamespace\MyClass:
        arguments:
            $logger: '@monolog.logger.my_channel'

I wonder why the injection by type does not work anymore.
