Oleg Gaidarenko b930d14ce6 Tests: partially use new qunit interface
http://qunitjs.com/upgrade-guide-2.x/

For most of the boring work was used
https://github.com/apsdehal/qunit-migrate package

However, it can't update local qunit helpers, plus in some places
old QUnit.asyncTest signature is still used

Fixes gh-2540
