All these ASSERTs are super redundant.  This is the only one that matters for
the whole fetch directory.  Maybe remove the others and keep this one?

Done. Also removed one ASSERT check before the new XSLStyleSheetResource
creation in ResourceFetcher.cpp. Should we also remove all the other ASSERTs
which are there in ResourceFetcher.cpp?
