[PATCH v4 4/4] test: add test for checking forwarded messages

[Örjan Ekeberg]

Add test of forwarding messages from within emacs.
The first test checks that a references header is properly
added to the new message.  The second test checks that the
send-hook of the forwarding message adds a forwarded-tag
to the original message.
