Try to decrypt any encrypted parts of newly-discovered messages while
indexing them. The cleartext of any successfully-decrypted messages
will be indexed, with tags applied in the same form as from notmuch
insert --try-decrypt=true.
Note: if the deprecated crypto.gpg_path configuration option is set to
anything other than "gpg", we ignore it (and print a warning on
stderr, if built against gmime < 3.0).
We also add a new test making use of this functionality. This
requires a bit of reorganization, because we need to allow passing
--long-arguments to "notmuch new" via emacs_fcc_message
