Title: Remove old schema migration code (pre-1.18)

The state.Open method was constantly looking to see if it needed to do a schema upgrade.

The comment indicates that this was done for the 1.18 release. We are now post 1.20, and this no longer makes any sense keeping around.

The initialize method has been updated to assert that the new stateServerC documents don't exist.
