Sort nodes by zone name instead of zone ID.

[Jeroen T. Vermeulen (jtv)]

That easy? What a relief! Django has its good sides, eh?

Instead of hard-coding zone names in the test, I'd just create a slightly longer list and let factory.make_zone() come up with names...

    zones = [factory.make_zone() for _ in range(5)]

The longer list will make it most likely that failures to sort will be exposed.

Okay, I'll do that. There's the possibility of false success, but it's low.

I'll also remove the TODO you added about this; I missed that.
