rpl.rpl_start_alter_chain_basic was used to fail sporadically due to a missed GTID master-slave synchronization which was necessary because of the following SELECT from GTID-state table. Fixed with arranging two synchronization pieces for two chain slaves requiring that. Note rpl.rpl_start_alter_restart_slave must have been fixed by MDEV-30460 and 87e13722a95a (manual) merge commit.
