pywb returns some HTML for pages not available and Google Analytics treat them as PageViews

[peterchanws]

Even though https://swap.stanford.edu/was/20141218230016mp_/http://mlk-kpp01.stanford.edu/kingweb/popular_requests/frequentdocs/birmingham.pdf displays a message saying it can't be found, pywb returns some HTML for the page, with Google Analytics embedded in it, so it thinks the user viewed the page just fine.

It would be better if pywb returns something which Google Analytics will not treat these cases as PageViews.
