This primarily affected the key's namespace, which was being derived from and
checked against AppID. On dev_appserver, the key namespace didn't match the
native datastore library's assigned namespace.

Now that I think about it, though, this is probably not correct. AppID is still
the same; just the "aid" value for the key is wrong. I'll update to apply this
logic in the "aid" generation.
