This commit has a mtr test where two two transactions delete a row from two separate tables, which will cascade a FK delete for the same row in a third table. Second replica node is configured with 2 applier threads, and the test will fail if these two transactions are applied in parallel. The actual fix, in this commit, is to mark a transaction as unsafe for parallel applying when it traverses into cascade delete operation. Reviewed-by: Jan Lindström <jan.lindstrom@mariadb.com>
