IsIterableContainingInOrder.contains(null, null) causes NullPointerException

[izat]

It just looks like the same exception as issue 25.

code:

    @Test
    public void testHamcrest() throws Exception {
        List<Integer> list = Arrays.asList(null, null);
        assertThat(list, IsIterableContainingInOrder.contains(null, null));
    }

output:

java.lang.NullPointerException
