fix(org): don't error org-download at top level

Org-attach (and thus org-download) can work before the first headline if
the user sets `org-attach-auto-tag` to `nil`. But when inserting files
in this situation, this advice will display an error message due to
using `org-back-to-heading`. So I think it makes more sense to use
`org-back-to-heading-or-point-min`.
