no issue
- after un-nesting the built-in integration routes they no longer had the automatic redirect for non-admins
- added our non-admin redirect behaviour to all of the integration routes
- added our non-admin redirect behaviour to the Zapier route which didn't even have an authenticated redirect previously
- added acceptance test for Zapier route so verify the new behaviour
- wrapped the Zapier widget `<script>` tag in an "is testing" conditional so that the external script doesn't get loaded during tests
