urlapi: make curl_url_dup() copy the guessed_scheme flag
curl_url_dup() copied port_present, fragment_present and query_present
but missed guessed_scheme, so a duplicated handle always reported an
explicit scheme. Applications relying on CURLU_GUESS_SCHEME plus
CURLU_NO_GUESS_SCHEME to reject bare hostnames after duplicating a
handle would silently accept them instead.

Verified in test 1989
