I'm not sure why some production systems have these (possibly they used to be created in some much earlier version and have lasted through upgrades), but they're not valid for raft leases so don't try to migrate them.

Description of change
These were causing errors reported from migrating the leases to raft during the upgrade. The leases wouldn't cause a problem other than a delay, because nothing would be extending them.
It's not clear why some production systems have these (possibly they used to be created in some much earlier version and have lasted through upgrades), but they're not valid for raft leases so don't try to migrate them.
