All QUnit tests fail in all browsers with:

Uncaught Error: pushFailure() assertion outside test context, was     at F.QUnit.start (.../qunit.js:464:10)`, unless I set `QUnit.config.autostart = false;

The problem is at: lib/hub/view/public/inject.js#L7:

// Do not start QUnit tests before bind,
// we need to setup logging callbacks first.
if (window.QUnit && window.QUnit.config) {
    window.QUnit.config.autostart = false;
}

This is executed when there is no QUnit in global space yet (inject.js is always the first script, in fact yeti makes sure it to be first) - code above has no chance to execute, ever.

So autostart is never disabled and QUnit.start() is run twice.
