Fix accidental deletion of queries and fragments from the fallback

Closes #19. This technique is inspired by the data: URL processor's initial steps: https://fetch.spec.whatwg.org/commit-snapshots/7307d282dd7d1293d5697d63f73522007849e0db/#data-url-processor. Whether or not this technique is ideal, is an open question. See whatwg/url#385.
