https://github.com/multiformats/js-multiaddr/pull/76 changed the
default protocol from ipfs to p2p.
js-multiaddr is a transitive dependency of peer-info, so in order
to get this change, we had to bump the version of peer-info.
* fix: revert ipfs -> p2p change for some tests
As per PR feedback. Needed for backwards-compatibility.
