When deprecating scoped modules, the /, is not escaped as %2f.

npm verb get saving @bcoe/hardwork to /Users/benjamincoe/.npm/registrytwo.npmjs.com/_40bcoe_252fhardwork_3Fwrite_3Dtrue/.cache.json
npm verb request uri https://registrytwo.npmjs.com/@bcoe/hardwork

npm http request PUT https://registrytwo.npmjs.com/@bcoe/hardwork
npm http 504 https://registrytwo.npmjs.com/@bcoe/hardwork
