Move integration-y unit tests into integration test system

[cap10morgan]

Some of our unit tests are more like integration tests and would benefit from being moved into that system. We should go over them and do that migration. Note that @heskew already did a great job of this for the server unit tests (in unitTests/server) in #113 so those are probably all set.
