Bug #53757 assert in mysql_truncate_by_delete
The assert was triggered if a connection executing TRUNCATE on a InnoDB table was killed during open_tables. This bug was fixed in the scope of Bug #45643 "InnoDB does not support replication of TRUNCATE TABLE". This patch adds test coverage to innodb_mysql_sync.test.
