Unlike the other migrations, this one uses a bare table name to specify the table. This means it looks in the default search path. Unfortunately, the out of box search path is:
1. Schema with the same name as the user
2. Public
Because of this, if a schema exists with the same name as the DB user, the playlist_videos table will get created in _that_ schema, rather than the public schema, and then the grant statement will fail with an error like below if check_table is enabled as it keeps trying to create the table but failing on the grant statement:
```

* Untrack config.yml
`config/config.yml` has been untracked and moved to `config/config.example.yml`.
The Dockerfile has been updated to copy all `config/config.*` files and to try
to move `config/config.example.yml` to `config/config.yml`. If a user supplied
`config/config.yml` exists it is not overwritten.
* Update Dockerfile to use `shard.lock`
* Fix tests
