open: fix mimetype discovery for encrypted or signed messages 

Mimetype discovery for the :open command is based on the BodyStructure
of the message. This patch fixes the method which got the BodyStructure
of the message to a more generalized one, which is set post-encryption
and post-validation. This allows encrypted or signed message parts to
have their proper mimetype discovered.
