KILL QUERY doesn't close already fetched cursor.
Reproducer:

{code:java}
    public void testCancelSQLQuery() throws Exception {
        startGrids(NODES_CNT);
        IgniteEx client = startClientGrid("client");

        client.cluster().state(ACTIVE);

        IgniteCache<Object, Object> cache = client.getOrCreateCache(
            new CacheConfiguration<>(DEFAULT_CACHE_NAME).setIndexedTypes(Integer.class, Integer.class));

        for (int i = 0; i < PAGE_SZ * PAGE_SZ; i++)
            cache.put(i, i);

        SqlFieldsQuery qry = new SqlFieldsQuery("SELECT _KEY, _VAL FROM INTEGER").setSchema("default").setPageSize(10);
        Iterator<List<?>> iter = queryProcessor(client).querySqlFields(qry, true).iterator();

        assertNotNull(iter.next());

        List<List<?>> sqlQries = SqlViewExporterSpiTest.execute(client,
            "SELECT * FROM SYS.SQL_QUERIES ORDER BY START_TIME");
        assertEquals(2, sqlQries.size());

        String qryId = (String)sqlQries.get(0).get(0);
        assertEquals("SELECT _KEY, _VAL FROM INTEGER", sqlQries.get(0).get(1));

        QueryMXBean qryMBean = getMxBean(client.name(), "Query",
            QueryMXBeanImpl.class.getSimpleName(), QueryMXBean.class);

        qryMBean.cancelSQL(qryId);

        //SqlViewExporterSpiTest.execute(client, "KILL QUERY '" + qryId + "'");

        while(iter.hasNext())
            assertNotNull(iter.next());

        fail("You shouldn't be here!"); //Fails here for now. but should fails on iter.next call.

{code}
