Add unit test for multihash panic in multiformats/multihash

[mattheworris]

Goal

The goal of this PR is to add a unit test in the messages pallet to detect a panic on some types of bad cids.
multihash v0.18.1 fixes an issue with calling unwrap() on certain types of errors in a no-std environment.
multihash is included by the cid crate used for IPFS messages.
[Cargo.lock was updated by another PR before this was merged, so v0.18.1 is already there]

Closes #1233

Further updates in progress #1417
multiformats/rust-cid#135

This is the crate version that fixes the panic.

[JoeCap08055]

I suggest bumping the dependency in Cargo.toml as well.

[saraswatpuneet]

if it is an indirect dependency we should be careful with updating the lock file

[JoeCap08055]

This will technically work, but it might be nice to submit a PR to https://github.com/multiformats/rust-cid/blob/master/Cargo.toml to bump the actual dependency there.

[JoeCap08055]

Then we could bump our cid dependency in Cargo.toml.
Meanwhile, approving--but maybe file a chore to follow up once the cid crate bumps the underlying dependency.

[mattheworris]

Yeah, the Cargo.lock file reflects the changes from executing cargo update, I did not edit the file directly.

[JoeCap08055]

@saraswatpuneet , it's not a manual update of the lock file; I think Cargo updated the indirect dependency based on the rules, now that multihash has published a version with the fix. But my previous comments stand--we should encourage the cid crate to update their dependency, and then update ours explicitly.
