Since we created the migration guide for the `missing-injectable` schematic, the schematic
changed in various ways. e.g. the migration no longer migrates classes passed to `useExisting`
Additionally the migration has been expanded to handle another Ivy breaking change where
providers like `{provide: X}` will be intepreted as `{provide: X, useClass: X}`. This pattern should
be documented in the migration guide.
