This was resulting in exceptions like the following when used with MySQL

", ".join(columns),
ValueError: Found wrong number (0) of constraints for
patchwork_seriespatch(series_id, number)
This error was being raised by the following lines in the 0033
migration:
migrations.AlterUniqueTogether(
name='seriespatch',
unique_together=set([]),
)
It appears that this is because of a mismatch between the order of
fields in a 'unique_together' constraint [1]. Correct the order in the
original migration and see the issue disappear.
