DEV: Clean up QUnit tests (PR #13328)

  • DEV: Use query helper instead of queryAll()[0]
  • DEV: Replace queryAll().length w/ exists()/count() (Just some of them. There are still 192 instances of queryAll.length)
  • DEV: Use exists() instead of count() > 0, count() === 0
  • DEV: Use count()/exists() instead of find().length
