[CRX] Avoid encoding the fragment in file key

Browse source 
Semantically, it is more correct to encode the fragment in the URL
instead of the URL-encoded `file` query parameter. This shouldn't matter
in practice, because `rewriteUrlClosure` in `chromecom.js` decodes the
`file` parameter and restores the fragment. However, as #16625 shows,
there was a case where this did not work as expected.
