Bram Moolenaar 2ec364e94d patch 8.0.1432: after ":copen" can't get the window-ID of the quickfix window 
Problem:    After ":copen" can't get the window-ID of the quickfix window.
            (FalacerSelene)
Solution:   Make it work without a quickfix list.  Add a test. (Yegappan
            Lakshmanan, closes #2541)
