If you don't want to provide patch according to 

http://notmuchmail.org/contributing/

(patch format & commit message are important to attract reviewers (who!?;) ))

and additionally explain (to me) why some of those things are changed to
symbols you can just edit

~/.emacs.d/notmuch-config.el

and add

(setq notmuch-address-selection-function
      (lambda (prompt collection initial-input)
        (completing-read prompt (cons initial-input collection) nil t nil 'notmuch-address-history)))

there (or use customize to do that (?)).

If I were smarter when I split this call out from notmuch-address-expand-name
I would not have called it with (car options) (cdr options) but split
it in that selection-function but that is how it is now...(*)

(*) Especially as I did that just so that I can do this:

(setq notmuch-address-selection-function
      (lambda (prompt collection initial-input)
        (selection-menu "Send To:" (cons initial-input collection) t)))
