Fix error getting allow_discussion  when p.a.discussion is not activated. (#1808)

* Fix error getting allow_discussion value when p.a.discussion is not activated.

This fixes an error in Plone 6.1 when the `plone.app.discussion` package is available but not activated in the Add-ons.
Problem is that the `conversation_view` is only defined when the browser layer of `plone.app.discussion` is found.
Sample error:

```

```

* Fix tests: Plone Site now gets allow_discussion false instead of null.
