fix QUnit to allow tests run from Java without Qore

[davidnich]

ex:

david@meteor:~/src/Qorus/git/qorus/test/java$ java -cp /Users/david/src/Qorus/test/jar/qorus-client.jar:/Users/david/src/Qorus/test/jar/qorus-test.jar:/Users/david/src/Qorus/test/jar/qore-jni.jar:. -Djava.library.path=/usr/local/lib TestJob
Exception in thread "main" org.qore.jni.QoreExceptionWrapper: RUNTIME-CAST-ERROR: cannot cast from type 'nothing' to 'list<string>'
	at org.qore.jni.QoreJavaApi.newObjectSave0(Native Method)
	at org.qore.jni.QoreJavaApi.newObjectSave(QoreJavaApi.java:178)
	at com.qoretechnologies.qorus.test.QorusJobTest.<init>(QorusJobTest.java:37)
	at TestJob.main(TestJob.java:11)

This is because there is no ARGV value when Qore is initialized from Java in QUnit.qm:732::

            p_argv = cast<list<string>>(ARGV);
