Auction API: Getting wrong realm auction batch

Hello,

On EU realms, when downloading the batch from the URL returned by the `/api/wow/auction/data/` call, I get the data for another realm:

ownerRealm seems to be correct, but realm.name is not.

Example:

```
$ curl http://eu.battle.net/api/wow/auction/data/medivh
{"files":[{"url":"http://eu.battle.net/auction-data/57304a565824f2d778f9ad106430c98c/auctions.json","lastModified":1412860949000}]}%

$ curl -s http://eu.battle.net/auction-data/57304a565824f2d778f9ad106430c98c/auctions.json | head
{
