Save mbox files with proper unixfrom

In order to avoid some of the more obscure charset encoding problems, we
switched to using as_string() for generating messages before saving them
in an mbox file. However, this uncovered a bug where the unixfrom was
not actually generated and saved, despite as_bytes() and as_string()
supposedly behaving identically.

See:
https://docs.python.org/3/library/email.message.html#email.message.EmailMessage.as_string

This commit fixes the problem by properly setting the unixfrom and using
the recommended (and hopefully less buggy) email.generator interface
when saving mailboxes.
