Before this fix, if you tried tagging the httpstats with a new tag, it wouldn't go through because the tags weren't initialized. That's because before this PR, we are passing the original request down to the wrapped handler and only initializing the tags on the responseWriter's reference to req.
Want to figure out how to test it before we merge.
