The call-process to notmuch in notmuch-query.el was previously sending
stderr into the output buffer. This means that if there is any stderr
the JSON parsing breaks. Unfortunately call-process does not support
sending stderr to a separate buffer or to the minibuffer [0], but it
does support sending it to /dev/null. So we do that here instead.
[0] a bug was filed against emacs (#7842)
