Bug Fixes

Fixed a false positive with schema errors when applying evolutions on MySQL.

When applying new evolutions along with baseline schemas for new models, two version history entries are created, one for the new baselines, and one for the new, final schema. On MySQL, this can happen so quickly that they’ll end up with the same timestamp (as there isn’t a lot of precision in these fields).

Due to internal sort orders, the next evolution then finds the version entry for the baseline schema, and not the final evolved schema, causing it to fail saying that there are changes that couldn’t be applied.

This fixes this problem by improving the sorting order.
Fixed issues evolving certain changes from old database schemas.

Old database schemas didn’t track certain information, like the index_together information. The code was previously assuming the existence of this information and failing if it wasn’t there. Evolving from these older schemas now works.
