For some reason, the migration path from unmanaged db (from alembic point-of-view) to managed db, through the initial migration works well with sqlite… But not with mysql where the db system tries to re-create the existing tables. This commit is a way to detect if we are migrating from pre-alembic era and skip the first migration (which would do nothing anyway), marking it as already executed. It's quite hackish but that's the best I found so far to get it working with both MySQL and SQLite.
