tests: Change handling of reading non blocked empty stream for python3

Browse source 
The result of reading non blocked empty stream is different between
python2 and 3. The python2 sends "[Errno 11] Resource temporarily
unavailable" exception. The python3 could read "None" without
exception, so handle this "None" case as well.
