apply-type-fns does not apply the function if the value is false about toucan

@jonathanjansen, that sounds like a bug for sure. There's probably somewhere in apply-type-fns where it's checking whether the value is truthy before applying the function, rather than checking whether it's non-nil. Should be a one-liner once it's tracked down. PRs welcome!

Thank you for the reply

Its the when-let
src/toucan/models.clj line 303

(defn- apply-type-fns
  "Apply the appropriate `type-fns` for OBJ."
  [obj direction]
  (into obj (for [[col type] (types obj)]
              (when-let [v (get obj col)]
                {col ((get-in @type-fns [type direction]) v)}))))

I will do a pull request over the week.
