Update MSTEST0037 to propose Assert.IsNotEmpty for more cases

[drieseng]

MSTEST0037 could also propose to use Assert.IsNotEmpty for the following code:

Assert.IsTrue(myList.Count > 0); // Assert.IsGreaterThan is currently proposed
Assert.IsTrue(myList.Count != 0); // Assert.AreNotEqual is currently proposed

Ideally, this would be reported for both generic and non-generic collections.

Note: I've created issue #6358 which contains a few more cases.
