31d7a09bf5c423ad2003d6863d7372e49a195af1 had a small issue resulting in a lack of proper registration of path to translation resources in installed bundles.

The issue is caused by the incomplete update of the code where the newly added `$transPaths` variable was not updated in all code branches ([1](https://github.com/symfony/symfony/blob/85d01657a1a1aa65f57d0e0077fc7a10466acdd8/src/Symfony/Bundle/FrameworkBundle/DependencyInjection/FrameworkExtension.php#L1330), [2](https://github.com/symfony/symfony/blob/85d01657a1a1aa65f57d0e0077fc7a10466acdd8/src/Symfony/Bundle/FrameworkBundle/DependencyInjection/FrameworkExtension.php#L1335), [3](https://github.com/symfony/symfony/blob/85d01657a1a1aa65f57d0e0077fc7a10466acdd8/src/Symfony/Bundle/FrameworkBundle/DependencyInjection/FrameworkExtension.php#L1340), but not [4](https://github.com/symfony/symfony/blob/85d01657a1a1aa65f57d0e0077fc7a10466acdd8/src/Symfony/Bundle/FrameworkBundle/DependencyInjection/FrameworkExtension.php#L1345))

The issue can be reproduced and tested like this:

```bash
composer create-project symfony/skeleton test
cd test
composer require easycorp/easyadmin-bundle
php bin/console debug:translation en --domain EasyAdminBundle
```

It will result in unexpected:

```
[WARNING] No defined or extracted messages for locale "en" and domain "EasyAdminBundle"
```

After applying the fix, clearing the cache and running the same command list of messages will be returned properly.
