cli: use new notmuch_crypto_get_context in mime-node.c

This has the affect of lazily creating the crypto contexts only when
needed.  This removes code duplication from notmuch-show and
notmuch-reply, and should speed up these functions considerably if the
crypto flags are provided but the messages don't have any
cryptographic parts.
