DoctrineMigrationToolsBundle not working with organize_migrations

[florianperreon]

Hi
This bundle does not work with this doctrine_migrations configuration :
doctrine_migrations:
organize_migrations: BY_YEAR_AND_MONTH

in this file : class DiffFileCommand extends \Doctrine\DBAL\Migrations\Tools\Console\Command\DiffCommand

this function : getLastSchemaDefinition($configuration)
is not good if SchemaVersion files are not in the same folder
$dir = $migrationDirectoryHelper->getMigrationDirectory().'/SchemaVersion';
=> will only search in the current month

For exemple :
2020/03/SchemaVersion/Schema202003********
2020/03/SchemaVersion/Schema202003********
2020/03/SchemaVersion/Schema202003********

And we are now in 2020/04

When we execute diff-file command : bundle consider that there is no LastSchemaDefinition : migration file is generated with all sql requests from a new database
