cli/help: give a hint about notmuch-emacs-mua

"notmuch help" doesn't mention "notmuch-emacs-mua" even though we
support it through the try_external_command() mechanism.

In addition, "notmuch help emacs-mua" doesn't work, even though we
ship the appropriate manpage.

This changeset fixes both of these problems.
