hugolib: Fix draft etc. handling of _index.md pages

We will need to revisit this with a proper spec, but this commit makes sure that draft/expiryDate etc. set in front matter on _index.md content files that should disable the page will:

* Not crash
* Make the rendered page not render any `.Content`.

Fixes #6222
Fixes #6210
