Couple of tweaks for org-publish backlinks function

[doubleloop]

After updating to 1.2.3 I noticed that my backlinks weren’t publishing during org-publish, using the org-roam--backlinks-list example function that was in the org-roam docs back in the day (which no longer seems to be there.)

Couple of updates required:

• function org-roam--get-title-or-slug has been deprecated (https://github.com/org-roam/org-roam/commit/face683e00c2fe6c45f6958f05bef1750e7372df). org-roam-db--get-title looks like the new way to do this.
• the backlinks query was using from and to which are now source and desc (https://github.com/org-roam/org-roam/pull/1213/commits/399c94b121a124a42493d713fd955cef58767100)

So the tweaked function I’m using now is:

(defun commonplace/org-roam--backlinks-list (file)
  (if (org-roam--org-roam-file-p file)
      (--reduce-from
       (concat acc (format "- [[file:%s][%s]]\n"
                           (file-relative-name (car it) org-roam-directory)
                           (org-roam-db--get-title (car it))))
       "" (org-roam-db-query [:select [source] :from links :where (= dest $s1)] file))
    ""))

I noticed here that @jethro has a slightly different function for this, so the general use of elisp there is probably better.

I no longer generate backlinks using Org-roam’s db: i just use Hugo’s templating functionality.
