Fix monitor possibly applying incorrect PG history under heavy load
...
Monitor could deceive itself by immediately saving PG configuration changes
which weren't applied to etcd yet in memory, and apply incorrect PG history
changes next time if the first update fails.
This usually only happened under heavy load and was caught in CI. :-)
