mysql-test/r/events_slow_query.result: fix result mysql-test/t/events_slow_query.test: create different event because the executor is buggy and won't catch the difference if the memory address does not change (will be reported as bug separately) sql/sp_head.cc: this was an error which passed code review. thd->enable_slow_log could be changed and it should not be relied
