When `->buildContainer()` throws because the cache directory cannot be created, we still try to write the deprecations logs inside the cache directory. In this case, the final exception is `Warning: file_put_contents(/app/var/cache/dev/App_KernelDevDebugContainerDeprecations.log): failed to open stream: No such file or directory` instead of `Unable to create the "cache" directory (/app/var/cache/dev).`.

Alternative:
```php
try {
    // ...
} catch (\RuntimeException $e)
} finally {
    if (isset($e)) {
        throw $e;
    }

    // ...
}
```
