org.el (org-refile): Allow org-refile goto from everywhere

* lisp/org-agenda.el (org-refile): Flip logic to allow instead of
  prohibit the use of `org-refile' with the goto flat from non
  org-mode buffers.

In commit 49da67d the condition was changed from only
`(unless goto ...)` to `(unless (and goto (listp arg)) ...)`
where the `and` condition is only true for non-empty lists, so that
calling `(org-refile t)` complains about not being inside an org-mode
buffer.

With this patch org-refile can be used (again) from anywhere when
passed the goto flag to jump to the chosen task.
