notmuch.el: convert sparse keymap to a list in notmuch-substitute-one-command-key-with-prefix

Browse source 
The previous version would crash when a key was bound to a sparse
keymap, since apparently these are not straightforward lists.  The
usage of map-keymap is a bit obscure: it only has side-effects, no
return value.
