[fix] bing: parsing result; check to see if the element contains links
This patch is to hardening the parsing of the bing response: 1. To fix [2087] check if the selected result item contains a link, otherwise skip result item and continue in the result loop. Increment the result pointer when a result has been added / the enumerate that counts for skipped items is no longer valid when result items are skipped. To test the bugfix use: ``!bi :all cerbot`` 2. Limit the XPath selection of result items to direct children nodes (list items ``li``) of the ordered list (``ol``). To test the selector use: ``!bi :en pontiac aztek wiki`` .. in the result list you should find the wikipedia entry on top, compare [2068] [2087] https://github.com/searxng/searxng/issues/2087 [2068] https://github.com/searxng/searxng/issues/2068
