## Description 

We have removed the ability to disable state accumulator v2 previously
by ignoring the config parameter
(https://github.com/MystenLabs/sui/pull/18786), however if a node that
had v2 disabled has been running since before this change without
shutting down, the old config would still be stored in memory. This PR
forces enabling of v2. Once we have reached the epoch change after all
nodes are running this code, we can safely merge
https://github.com/MystenLabs/sui/pull/18764.
