Links should not be printed as {"code":85,"version":1,"hash":{"0":0,"1":0}}}}

Bunch of errors produce unreadable messages because links are not serialized properly. That is because CIDs define links as follows https://github.com/multiformats/js-multiformats/blob/15c52c8a5384e1bc84cccfa34ed6c7a78eb23978/src/cid.js#L202-L208 where bytes gets serialized as on object containing each byte.

I have submitted issue to multiformats multiformats/js-multiformats#228, but in the meantime we could workaround this via JSON.stringify replacer function which can substitute { code, version, hash } as needed.
