Re: Lua filter to remove captions from tables

[Albert Krewinkel <albert+pandoc-9EawChwDxG8hFhg+JK9F0w@public.gmane.org>]

I didn't test it, but I believe this should prevent the error:

    elem.caption = {long = {}}

I feel like BPJ's version is morally correct, so I'll create a PR that
would allow it.
