fix: properly serialize CID instances

The CID version agnostic tests ipfs-inactive/interface-js-ipfs-core#413 identified some functions were not properly serializing CID instances. This PR adds `cleanCID` step to several functions and also updates the `cleanCID` function to not assume buffer CIDs are CIDv0 multihashes.
