PostGraphileRelayPreset does not eliminate Row in ByRowId

Extracted from #2077.

---

PostGraphileRelayPreset is suggested as a way to hide the ugly rowId from your schema. This does work. However, connections are still generated using the ByRowId syntax. Even worse, it seems generated ByRowId connections do not actually expect the rowId after enabling PostGraphileRelayPreset! Instead, the value returned from the id is expected. This becomes confusing very quickly.

Current:

mutation {
  createIndividual(
    input: {individual: {profileByRowId: "WyJQcm9maWxlIiwiZjVmOWNiNWEtN2Y1Mi00MzgyLWE3ZDgtMzdkOWZhY2Q5NjJkIl0="}}
  ) {
    individual {
      id
    }
  }
}

Expected

mutation {
  createIndividual(
    input: {individual: {profileById: "WyJQcm9maWxlIiwiZjVmOWNiNWEtN2Y1Mi00MzgyLWE3ZDgtMzdkOWZhY2Q5NjJkIl0="}}
  ) {
    individual {
      id
    }
  }
}
