QueryExec: abort before exec is ignored.

[Aklakan]

Version

5.1.0-SNAPSHOT

What happened?

The following test does not raise the expected QueryCancelledException, in fact, abort() is ignored.

    @Test(expected = QueryCancelledException.class)
    public void test_Cancel_API_5() {
        Model model = ModelFactory.createDefaultModel();
        model.add(RDF.type, RDF.type, RDF.type);
        try (QueryExecution qe = QueryExecutionFactory.create("SELECT * { ?s ?p ?o }", model)) {
            qe.abort();
            ResultSetFormatter.consume(qe.execSelect());
        }
    }

Note, that because abort may be called asynchronously, abort signals must be handled even if the e.g. the thread that called execSelect() has not finished the internal QueryIterator setup yet.
