Change Details

Acceptance criteria: * When a page is deleted from a wiki, it's assessment data is also deleted from the page_assessments table. * When a page (and it's corresponding talk page) is restored on a wiki (undeleted), it's assessment data is restored to the page_assessments table. This may already be handled by the ParserFirstCallInit + OutputPageParserOutput hooks, but if not, we may need to add additional hook handlers for when a page is deleted or restored.
