The test is shutting down InnoDB, corrupting a file, and finally restarting InnoDB. Before the shutdown, the test created the table and inserted some records. Before MDEV-12288, there would be no access to the table after server restart, but after MDEV-12288 purge would reset the transaction identifier after the INSERT, and this would sometimes happen after the restart. To make the test deterministic, wait for purge to complete before the shutdown.
