MDEV-31651 : Assertion wsrep_thd_is_applying(thd) && !wsrep_thd_is_local_toi(thd) in wsrep_ignored_error_code

Problem was that with BINLOG-statement you can execute
binlog events on master also (not only in applier).
Fix removes too strict part wsrep_thd_is_applying from
assertion. Note that actual event in test is intentionally
corrupted to test should this error being ignored.
