patch 8.2.0934: lhelpgrep twice in help window doesn't jump to the help topic

Browse Source 
Problem:    Running lhelpgrep twice in a help window doesn't jump to the help
            topic.
Solution:   Check whether any window with the location list is present.
            (Yegappan Lakshmanan, closes #6215)
