Bug #53757 assert in mysql_truncate_by_delete

Browse source 
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.
