Bug: JSONP doesn't return procedure name

This bug is observed on the realm status feed and the character feed, so it probably affects all feeds.

Load this url:
http://us.battle.net/api/wow/realm/status?jsonp=abc

Observed:
({"realms":[{"type":"pvp","population":. ... }]});

Expected:
abc({"realms":[{"type":"pvp","population":. ... }]});

Since the EU site didn't get converted to 5.0.4 yet, it still works:
http://eu.battle.net/api/wow/realm/status?jsonp=abc
abc({"realms":[{"type":"pvp","population": ... }]});
