[5.1.x] Fixed #34856 -- Fixed references to index_together in historical migrations.

2024-12-17T09:01:51Z

While AlterUniqueTogether has been documented to be still allowed in historical migrations for the foreseeable future it has been crashing since 2abf417c815c20 was merged because the latter removed support for Meta.index_together which the migration framework uses to render models to perform schema changes. CreateModel(options["unique_together"]) was also affected. Refs #27236. Co-authored-by: Simon Charette Backport of b44efdfe543c9b9f12690b59777e6b275cb08103 from main.
