patch 8.0.1482: using feedkeys() does not work to test completion

Problem:    Using feedkeys() does not work to test Insert mode completion.
            (Lifepillar)
Solution:   Do not check for typed keys when executing :normal or feedkeys().
            Fix thesaurus completion not working when 'complete' is empty.
