make org-make-toc error message less intrusive

For most of my docs I use this mode so I set
```elisp
(add-hook 'org-mode-hook #'org-make-toc-mode)
```

But not for all... In that case I get this error on every save, which is annoying:
```
"org-make-toc: No TOC node found."
```

Is there a way to make `org-make-toc` check whether there's a `:CONTENTS:` drawer at its start and if not, give up silently?
