Add some tests covering ThreadItem::getHTML() and related methods

* ThreadItem::getText
* CommentItem::getBodyText (used when generating notifications)
* ThreadItem::getHTML (may soon be used in API)
* CommentItem::getBodyHTML (may soon be used in API)
* ImmutableRange::cloneContents (the common implementation for all
  of the above)

The outputs are only lightly reviewed. This is mostly meant to
document the current behavior rather than the expected behavior,
to avoid making unintentional changes while refactoring.
