[BUG] org-refile-get-location a symlinked file [9.7-pre (release_9.6.29-1443-gb4d17c)]

[Al Haji-Ali]

I have `org-refile-use-outline-path` set to t, expecting that when refiling, 
the filename should not appear in the list. However, because I am opening an 
org file using a symblink and I have `find-file-visit-truename` set to `t`, the 
test

`(not (equal filename (nth 1 x)))`

in `org-refile-get-location` always fails and the filename is displayed even 
when the current buffer and `(nth 1 x)` point to the same file. If I replace 
this condition by

`(not (equal (file-truename filename) (file-truename (nth 1 x))))`

The filename is not added to the list of refile targets as I would expect.
