Fix migrating old databases not containing certain metadata.

Django Evolution
release-0.7.x

Reviewers

Older databases don't have things like index_together stored in the
schema, which django-evolution looks for these days. This could cause
breakages when upgrading older databases. We now fall back to defaults
if these don't exist.

Unit tests pass.

I was able to upgrade some very old databases.
