[sup-talk] Fixing header for encrypted messages (might be an old issue)

[Christopher Bertels]

Hi!

I've been having problems with encrypting messages. No idea where this
came from, but somehow the protocol part in encrypted messages had an
extra pair of quotes, e.g.: protocol=""application/pgp-encrypted""
which caused it to not be recognized by some clients (e.g. mutt as far as I know).

Here's a simple fix. I have no idea, why this suddenly came up. Might
be that it had been like this all the time, just no one had a problem
with it? (I highly doubt that though!)  

If this is an old issue and I'm just using an old version, feel free
to ignore this. I've tried using the current master or next branch,
but that causes a crash when trying to open encrypted emails. Maybe
someone else is having a similar problem?

Greetings,
Christopher.
