I'm trying to rename a field on my user type:```ownedCourses: [Course!]! @relation(name: "AuthorOnCourse") @rename(oldName: "courses")```

@lastmjs this looks like a bug in the schema migration, could you please add an issue here: https://github.com/graphcool/api-bugs/issues?

You can rename it in the UI in the relation popup
