Temporarily disable tests that started failing post-maven

Joel is working on these failures in a separate branch. Since
maven (currently! we're working on this..) won't run the whole
test suite to completion if there's a failure early on, we need
to temporarily disable these tests in order to allow group members
to run tests on their branches again.
