[fix] ddg engine: IndexError exception is raised on empty contend (#4843)

Browse Source 
Sometimes (e.g. when ddg does not have a result item) there is no content and
the engine will fail with an IndexError:

  * Error: IndexError
  * Percentage: 10
  * Parameters: `()`
  * File name: `searx/engines/duckduckgo.py:375`
  * Function: `response`
  * Code: `item["content"] = extract_text(eval_xpath(div_result, './/a[contains(@class, "result__snippet")]')[0])`
