Migrate to JUnit 4.8.1

This is the latest release available on the maven repo.

Maven surefire plugin for JUnit4 does not like when a class that
contains Test in its name has no @Test annotated methods. To fix
this issue I renamed the class TestDatabase -> InMemoryDatabase.
See http://jira.codehaus.org/browse/SUREFIRE-482 for more information.
