Python3 json can not work with bytes type input so used simplejson
instead of python json which works with both bytes and unicode
type input.
Previously we mistakenly updated StringIO to six.String io. which
caused the tests failure. Used io.BytesIO to fix the issues as
assci character bytes can not be converted to unicode.
This fixes errors like:
