test failures run from 1.7; test_serialize, test_simple_migration

[Ian Delaney]

There's another issue opened a week ago re test_serialize however the commit/patch that declares the fix doesn't take.

under all pythons. I expect you'll tell me it passes fine.

I haven't seen failures like this. Can you try to debug the failures yourself or at least provide more details about your OS, etc? It seems like the isinstance(value, datetime.datetime) check in django.db.migrations.writer isn't working for some reason.
