          Description

          When a temporary error is encountered on the slave (like deadlock), the
          transaction is retried.

          But one of the patches for MDEV-4506, parallel replication, broke this. The
          transaction is still retried, but the error is not cleared from SHOW SLAVE
          STATUS, which can cause problems later.

          There is a test case rpl_temporary_errors that is supposed to test this and
          catch any regressions, but that test is broken by some old 2007 idempotency
          stuff and does not actually test anything, which allowed this to slip through.
