…usciel)

This PR was merged into the 1.0-dev branch.

Discussion
----------

Despite the note: `Namespace is arbitrary but should be different from App\Migrations as migrations classes should NOT be autoloaded`, the current Sylius Standard configuration suggests `App\Migration` as a namespace(ref. https://github.com/Sylius/Sylius-Standard/blob/master/config/packages/doctrine_migrations.yaml#L6). What is more, this namespace is not an issue anymore: doctrine/DoctrineMigrationsBundle#242.

Without this change, current migration will not work automatically during plugin installation.
