 Title: #995: py3: handle bytes in schema response
Action: opened

PR body:
"""
If a server is running under py2 it could return a bytes value for
the 'topic_topic' field in the schema response.  A py3 client fails
to handle this (in one place it applies 'str' to it, which raises
BytesWarning; in other places it tries to serialise the schema to
JSON which fails because of the bytes value).

Handle the case where 'topic_topic' is not unicode, and handle bytes
values when serialising the schema to JSON.
