Fix a race between RewriteContext::FetchContext::HandleDeadline calling OutputResource::UrlEvenIfHashNotSet in normal rewrite thread and a filter calling OutputResource::BeginWrite via ResourceManager::Write in a low-priority rewrite thread by removing some logging. This is hard to trigger now, but will be more common once fetches use low-priority rewrite thread.
