Unqualified asyncTest with assert argument results in two assert arguments to test callback

[platinumazure]

Test case:

asyncTest("Test name", function (assert) {
    ok(true);
    start();
});

Expected:

QUnit.test("Test name", function (assert) {
    var done = assert.async();
    assert.ok(true);
    done();
});

Actual:

QUnit.test("Test name", function (assert, assert) {
    var done = assert.async();
    assert.ok(true);
    done();
});

Also probably happens with unqualified test.
