Title: Handle hash with string keys returned from faraday-http-cache

I'm using [faraday-http-cache](https://github.com/plataformatec/faraday-http-cache) with Redis but the parsed JSON hash return from the cache is not symbolised and caused Her to throw Nil errors. #192 does not fix all the problems.
