The SQLite schema editor doesn't handle `index_together` changes. This
manifests itself when renaming a field that is part of `index_together`.
I came across the bug when fixing
https://code.djangoproject.com/ticket/23859#comment:6 . After
`RenameField`'s `database_forwards()` has run the index is missing.
