DoctrineORMModule: --dry-run and --write-sql does not output the SQL statement to display.

Cause is outputWriter of doctrine/migrations is the closure of the null by default.

How can I set the closure of its own?

To try, I tried to modified as follows.

'migrations_configuration' => array(
    'orm_default' => array(
        'outputWriter' => call_user_func(function() {
            $output = new ConsoleOutput();
            return new OutputWriter(function($message) use ($output) {
                $output->writeln($message);
            });

        }),
    ),
),

MigrationsConfigurationFactory.php

$configuration = new Configuration($connection, $migrationsConfig['outputWriter']);
