Fix Pass condition for "static" routes
Fix Pass condition for "static" routes

Previously we relied on the static directory to construct the pass condition, but this doesn't include many things added to the build other than static files. So instead of adding these explicitly through `extraAppRoutes`, base the Pass condition on the final build, but exclude the view .html files. This way the version.txt, routes.json, and all directories added by webpack will be resolved to S3 rather than scratchr2.
