This PR updates to interface-ipfs-core": "^0.118.0 which includes test for resolving paths with libp2p-key represented as CIDv1 Base32.

Open Problem

The problem is that go-ipfs 0.4.22 does not support PeerID as CID, so test added in ipfs-inactive/interface-js-ipfs-core#553 fails:

  1) interface-ipfs-core tests
       .name.resolve offline
         should resolve a record from peerid as cidv1 in base32:
     Error: not a valid proquint string

@alanshaw not sure how to handle this. Wait for go-ipfs v0.5.0? Fixup on the fly in the meantime?

A hacky way to support CIDs when API is go-ipfs 0.4.22 or older is to convert toBase58btc before sending. See below.

For now we skip cidv1b32 test, added todo to unskip when go-ipfs ships with native support.

closes #1147

This is a hacky way to support CIDs when API is go-ipfs 0.4.22 or older

// normalize PeerIDs to Base58btc, so it works with go-ipfs <=0.4.22
if (typeof (args) === 'string') {
try {
const path = args.split('/')
if (path.length > 2) {
path[2] = multihash.toB58String(new CID(path[2]).multihash)
args = path.join('/')
}
} catch (err) {
// noop
}
}

All we need to do is stringify args if it is a CID. We will skip the interface-ipfs-core test here until go-ipfs supports it.

We don't stringify CIDs anywhere else, removed this hack and added TODO to unskip mentioned test when go-ipfs implements this.

Ah interesting, I guess the querystring module calls toString on the CID then...

Please would you add the updated interface-ipfs-core dep here and skip the relevant test?
