Missing decode() when assigning the schema in query event

Hi, I'm porting pg_chameleon to python 3.5 and I've noticed the binlogevent.schema assigned in the query event is not decoded like it is in the rowevent.

Many thanks

Start at pymysqlreplication/event.py around line 138 and compare how schema is assigned in the query event with the rowevent path. Verify the relevant replication-event behavior; the issue is done when query events expose the decoded schema consistently with row events.
