…upgrades Reference: hashicorp/terraform-provider-aws#8828 Prior to Terraform 0.12, providers were not required to implement the `MigrateState` function when increasing the `SchemaVersion` above `0`. Effectively there is no flatmap state difference between version 0 and defined `SchemaVersion` or lowest `StateUpgrader` `Version` (whichever is lowest) when `MigrateState` is undefined, so here we remove the error and increase the schema version automatically.
