Replace database queries in repositories with Morphia

I don't believe it is enough of a test. I would like to rewrite many of the existing unit tests to use the database rather than just stub it out. Alternatively I could write tests just for the repositories, but the repositories. I did feel this was a good start to begin working with Morphia/Mongo rather than the embedded XML. These tests are an improvement over what was already present. I'd like to continue to incrementally add more and more tests.
