Storing the injector in the InMemoryDatabase instance was a hack. Instead, move towards a more comprehensive Guice stack for tests by moving this setup into a module. Keep the same manual create()/drop() behavior of InMemoryDatabase, though eventually we may want to do something with LifecycleManagers and move towards a similar idiom to that used in the acceptance tests.
