feat: Don't copy References and In-Reply-To to outer headers

Based on #7405 actually (look a the last commit only) This is an experimental PR implementing the suggestion from https://www.rfc-editor.org/rfc/rfc9788.html#name-offering-more-ambitious-hea of "Header Protection for Cryptographically Protected Email".

So, only two tests on partial downloads broke, but this will be fixed by pre-messages anyway. Would be good to remove these outer heaaders as well, this way an eavesdropper can't group encrypted messages into chats/threads.

EDIT: This is based on the PR which can't be merged right now, so marking as draft as well.
