public function ViewExecutable::startQueryCapture in Views (for Drupal 7) 8.3

Set up query capturing.

db_query() stores the queries that it runs in global $queries, bit only if dev_query is set to true. In this case, we want to temporarily override that setting if it's not and we can do that without forcing a db rewrite by just manipulating $conf. This is kind of evil but it works.
