Fix #1897: Add tests for ItemSelectionInputDoesNotContainAtLeastOneOfRuleClassifierProvider

[fsharpasharp]

Explanation

Fixes #1897. This PR adds the missing test file for ItemSelectionInputDoesNotContainAtLeastOneOfRuleClassifierProvider. I copied the ItemSelectionInputContainsAtLeastOneOfRuleClassifierProvider by changing the assertions since it provides the negation of the same functionality.

Thanks @fsharpasharp! The new tests look quite good--I have some suggestions to improve test clarity slightly, and some ideas for additional tests.
