Bug: (bug?) org-id-find-id-in-file doesn't close files after finding id [9.4 (9.4-7-g3eccc5-elpaplus @ ~/spacemacs/elpa/develop/org-plus-contrib-20200921/)]

------------------------------------------------------------------------
** what happened
when running org-id-find-id-in-file on an id and an unvisited file, the
buffer it creates to visit file isn't
closed after finding id.

** what should have happened
I was expecting it to close the buffer if the
file wasn't already visited by another buffer.

Is this desired behavior?

** background info and possible fix
I stumbled on this while looking at an issue with org-roam at
https://github.com/org-roam/org-roam/issues/1129.

For now a guard clause like the following in the calling function closes the
buffer if need be.

      (let (file-already-open-p return-val)
        (setq file-already-open-p (find-buffer-visiting file))
        (setq return-val (org-id-find-id-in-file id file markerp))
        (unless file-already-open-p (kill-buffer (find-buffer-visiting file)))
        (print return-val))

This logic can be propagated to the function to squash this possible
bug.
