Rule proposal: no-empty-description

[pustovitDmytro]

Hi, that's would be awesome to catch empty suites/tests.

test('', function () {
    assert.equal(2 + 2, 4);
});

Of course, I can use valid-suite-description/ valid-test-description rules to enforce descriptions format, but I don't have a specific convention, and a lightweight no-empty rule will be useful for such a case.

I'm ready to provide help with implementation, if needed.

I think that is a great idea 👍.
