Describe the bug
Statement.getLargeUpdateCount() must return value, but throws an exception.

To Reproduce

        String sql = "create or replace table simple_test_2856371(col integer)";
        String url = "jdbc:databricks://...";

        Properties props = new Properties();
        props.setProperty("user", "token");
        props.setProperty("password", "<token>");

        Driver driver = DriverManager.getDriver(url);

        try (Connection conn = driver.connect(url, props);
             PreparedStatement st = conn.prepareStatement(sql)) {
            boolean isResultset = st.execute();
            assert(!isResultset);

            // Not the result set, get the update count.
            long updateCount = st.getLargeUpdateCount();
            assert(updateCount == 0);

            // Check for more results, stop condition is: ((stmt.getMoreResults() == false) && (stmt.getUpdateCount() == -1))
            // as specified in https://docs.oracle.com/javase/8/docs/api/java/sql/Statement.html#getMoreResults--
            isResultset = st.getMoreResults();
            assert(!isResultset);

            // must be -1, got an exception: Operation not allowed - ResultSet is closed
            updateCount = st.getLargeUpdateCount();
            assert(updateCount == -1);
        }

Expected behavior
Statement.getLargeUpdateCount() returns -1 when there are no more results.

Client Environment (please complete the following information):
Driver version: 3.0.3
