      Description

      Found while writing the tests for SERVER-31392, the DocumentSourceChangeStream hits a uassert when the UUID in the oplog entry mismatches the UUID in the scoped collection metadata. Returning ErrorCodes::StaleConfig results in a dynamic_cast a few layers up, and eventually an invariant. I am not sure we should hit this uassert at all (a separate discussion), but for sure it doesn't seem like we should be returning this status.
