Do not use go-message functions to parse Message-ID, References and
In-Reply-To headers. These functions are very pedantic about RFC
compliance which leads to insane slowdowns when aerc deals with non
RFC-compliant emails.
Use a broad regular expression to match anything that looks like
a message ID. The added lenient functions cannot fail.
