[BUG] Notmuch keeps adding notmuch-address-expand-name to message-completion-alist

[Attic Hermit]

You can get rid of the bug by using `member` instead of `memq` in
`nomtuch-address-setup`:

diff -u a/notmuch-address.el b/notmuch-address.el

-      (unless (memq pair message-completion-alist)
+      (unless (member pair message-completion-alist)
 	(setq message-completion-alist
 	      (push pair message-completion-alist)))))
