sjaakola 64e1dda0a0 MW-416 DDL replication moved after acl checking ...

galera_events test shows a regression with the original fix for MW-416
Reason was that Events::drop_event() can be called also from inside event
execution, and there we have a speacial treatment for event, which executes
"DROP EVENT" statement, and runs TOI replication inside the event processing body.
This resulted in executing WSREP_TO_ISOLATION two times for such DROP EVENT statement.
Fix is to call WSREP_TO_ISOLATION_BEGIN only in Events::drop_event()
