This isn't quite accurate. Loader items for the missing resources are created.
The assertion trips because when the resource fails to load,
FrameLoader::didFailToLoad() is invoked twice, once from
ResourceLoader::didFail(), then another time from ResourceLoader::didCancel().
In the first time, the identifier is removed from the map. Thus in the second
time, it's missing and the assretion fails.
