Update tests to incorporate sample use of new matcher support in Apex Mocks

[jondavis9898]

The blog post at http://superdupercode.blogspot.com/2016/03/apex-mocks-matchers.html is a great way for consumers of Apex Mocks to learn about the new features of Matcher support (which is awesome btw!).

I think it makes sense to update sample code to demo the usage as well. Thoughts?
