Log reponse content when UnicodeDecodeError occurs

Mateusz Żebrak requested to merge mzebrak/log-on-request-decode-fail into master

During CI there could be some random fails observed while trying to decode reponse. Unfortunately the error message doesn't say much so this commit adds some logging to see what the real content was.
