Anything that causes an OutdatedDataError currently returns a 500 error. This isn't right because the server hasn't done anything wrong - the client simply lost a race. The annoying thing about this is that Sentry gets notified of each one of these without good reason. The client retries anyways, so these aren't really indicative of a problem. Looks like 409 ("Conflict") is the right thing to send.

In bug 922625 we started sending a 400 for them. 409 might be better, but it really doesn't matter in reality...
