Add JavaQueryParticipantTest.java to the set of excluded tests, since they fail consistently in AbstractGWTPluginTestCase setup.
Add JavaQueryParticipantTest.java to the set of excluded tests, since they
fail consistently in AbstractGWTPluginTestCase setup.

Since disabling this test, I've had 3 successful runs of the tests, after
seeing this fail a half dozen times in a row. But looking at the code it is
hard to see why this fails more reliably than some other tests.

Here is the relevant stack trace:

It looks like the root cause is that the GdtPlugin needs to be activated
to acomplish some setup, but it is doing a lot of asynchronous things
that are likely problematic on their own but are breaking badly in tests.
