[PATCH 05/15] tests: Make sure all emails have a valid msgid

[Finucane, Stephen]

> Messages ids will be used by the Series code as the way to uniquely
> identify series. We must ensure every single email that goes through the
> parser has a valid msgid to not fail once we parse series.

> v2: Rebase on top upstream

I don't see anything similar, so some tests that test the code path of a missing message ID would be good to have. That's an extra commit though so:
