Sometimes, in MariaDB Server 10.5 but apparently not in later branches, the test would hang because con1 and con2 would be blocked in debug_sync (for example, lock_wait_suspend_thread_enter and row_ins_sec_index_entry_dup_locks_created) and therefore blocking the purge of transactions from completing. To prevent an occasional DEBUG_SYNC induced hang in the test, we will wait for everything to be purged, except the last 2 transactions. This change should be null-merged to 10.6, because the test is not failing in 10.6 or later major versions.
