Test fix for MDEV-6076 Persistent AUTO_INCREMENT for InnoDB

Before killing the server, ensure that the redo log for the
incomplete transaction is flushed, so that the AUTO_INCREMENT
sequence will always be updated. Usually the INSERT
transaction would not have persisted the sequence before the
server was killed, but sometimes it could happen, causing
result mismatch.

Note: This test used to be called innodb_fts.innodb_fts_misc_debug.
