Fix renumbering for footnotes at BOL.

Hi all,

org-footnote-renumber-fn:N invalidates footnotes that appear as the
first thing on a line.  Here's a test file including the recipe.

--8<---------------cut here---------------start------------->8---
* Bla

  This is a line in which the following footnote that is inserted exactly
  [fn:1] is the first thing in that line.  And now invoke
  org-footnote-renumber-fn:N and see it breaking.

* Footnotes

[fn:1] Test
--8<---------------cut here---------------end--------------->8---

Note, that in larger org files, it's likely that you don't even notice
that the footnotes break.

Once I added a patch on patchwork that fixed this issue, and that's
shown as "accepted".

I think, I've marked it as deferred or so myself because I've thought
the issue was fixed in the meantime, but that doesn't seem to be true.

Here's an updated patch.
