Our otr-bot.py does not use logging but the jabberbot library makes
logging calls,  causing a one-off message “No handlers could be found
for logger "jabberbot"” to be printed to the console. This commit
effectively prevents logging/outputting anything to the terminal which
is at a level lower than CRITICAL.

Will-fix: 9375
