ApiDiscussionToolsPageInfo and ApiDiscussionToolsCompare in direct parsoid
or VRS modes tries to fetch HTML using VisualEditor thus stashing the
HTML gotten which we don't want, we only need it for viewing in these cases.
This seems like something that was/is already happening in RESTBase. So for
APIs in DiscussionTools that need the HTML for viewing, just get it from
parser cache and not stash it.
