[fix] engine: duckduckgo - only uses first word of the search terms 

during the revision in PR #3955 the query string was accidentally converted into
a list of words, further the query must be quoted before POSTed in the ``data``
field, see ``urllib.parse.quote_plus`` [1]

[1] https://docs.python.org/3/library/urllib.parse.html#urllib.parse.quote_plus
