Bug fixes

• On accounts using the QuickSight Standard edition, AWS > QuickSight > Account Settings > Discovery no longer goes into error with Operation is disabled for STANDARD Edition, and now ends in ok. It still reports error for other access problems, such as a missing permission or an AWS > QuickSight > Connection Region policy set to the wrong region.
• On accounts that have not signed up for QuickSight, AWS > QuickSight > VPC Connection > Discovery no longer goes into error with Account information for account <id> is not found, and now ends in ok, as the other QuickSight Discovery controls already do.
