Wow. It turns out that this test will erase everything from the local
dev server's datastore!
Not calling the helper's tearDown() fixes that, but I hadn't checked
in that change since the test still doesn't succeed in getting App
Engine to update datastore-indexes-auto.xml.
Now it no longer calls tearDown(), and it configures the
LocalDatastoreServiceTestConfig to use the location "WEB-INF/appengine-
generated/DatastoreIndexTest_local_db.bin", and the test has @Ignore
since it doesn't work anyway.
