ContentRepliesView can be passed opts.contentIsVisible, a function that ...

...will determine whether to show new replies in the list. A default function is provided by main

This fixes a bug where ContentThreadViews, by default, would render contentViews for pre-moderated content, and the .body would be 'undefined', causing ugliness.

Reproducible here.
