commands: thread: Reference existing message when forwarding

When forwarding a mail, the outgoing mail, and any follow up conversation becomes a disjointed thread. This removes the original context, and makes it harder to find and track while the conversation splits in two directions. Add appropriate reference headers to the envelope when constructing a forwarded mail to ensure that the conversations continue to be related and therefore presented in the same thread with notmuch and alot.
