fix(upload-api-stack): don't add domain to apiID on first zone (#420)

# Goals

resolve
https://console.seed.run/dag-house/w3infra/activity/stages/staging/builds/386/services/upload-api

Essentially cause the up.web3.storage domain apiID changes, it tries to
recreate the domain record, and it can't. So the solution is don't
change the API ID for the web3.storage domain.

# Implementation

In order to match the existing deployment, this PR will not add the
domain to the first API ID for the first hosted zone.
