Investigate classfiles emitted to test/

[arrdem]

Not sure what I broke (shock, horror, yes I break stuff) but as of right now test runs emit classfiles into the test/ where cleaning them out is a bit of a pain. Should really dig into the test suite and figure out how and when the file emission bindings are being set, and make sure that the only generated classfiles wind up in target/ where they belong if they belong anywhere at all.
