Catch bad peerid and update deps

[jacobheun]

Doing some stability tests on ipfs using the latest libp2p I received an error trying to get the peer id from and address. The error is below. If the circuit dialer gets an address that is lacking a peer id, it will attempt to construct the id, but does not catch errors if the id is invalid. This PR fixes that by wrapping the PeerId creation in a try catch. I've added a test verifying the issue and fix.

This also updates dependencies.
