`org-add-note` only sets up a side buffer to write the content of the
note. The "go back to the heading to actually write the note" is done by
`org-store-log-note`, invoked using C-c C-c on your note.

So it is normal that `org-back-to-heading` fails in the org-note buffer
that indeed does not have a heading.

Hint: press p when in edebug session to find out in which buffer context
the code will apply.

I just tried applying the advice to `org-store-log-note` instead of
`org-add-note` and it worked fine :-).

My best,
