Init of the migration_versions table

How to populate the `migration_versions` table on (first) database setup?

Actually the `reset.sh` only [write the latest version](https://github.com/openl10n/openl10n/blob/master/reset.sh#L16) of the migration in the table. But the `doctrine:migration:migrate` command will execute all migrations not present in the table, even the migration before the latest one.
