emacs: help: check for nil key binding

A standard way to unset a key binding is local-unset-key which is equivalent to
  (define-key (current-local-map) key nil)

Currently notmuch-help gives an error and fails if a user has done this.

To fix this we only add a help line if the binding is non-nil.
