[BUDI-6670] Database name cannot be undefined when starting budibase with nginx ingress disabled via helm chart

Checklist

[ * ] I have searched budibase discussions and github issues to check if my issue already exists

Hosting GKE v1.21 cluster, latest helm chart install.

Describe the bug

Navigating to port forwarded app-service, nothing is shown on page. Backend logs throw an error:

[correlationId=aaa4ab6c-34b6-4747-9883-b0fcb29f6253] [tenantId=default] Trace: [correlationId=aaa4ab6c-34b6-4747-9883-b0fcb29f6253] [tenantId=default] Error: Database name cannot be undefined.

Couchdb container logs report continuously:

[error] 2023-03-02T13:56:03.202211Z couchdb@budibase-couchdb-0.budibase-couchdb.budibase.svc.cluster.local emulator -------- Error in process <0.603.0> on node 'couchdb@budibase-couchdb-0.budibase-couchdb.budibase.svc.cluster.local' with exit value:

Manually creating the _users table in couchdb silences the error in the logs, instead they log repeatedly:

[notice] 2023-03-02T14:03:18.720870Z couchdb@budibase-couchdb-0.budibase-couchdb.budibase.svc.cluster.local <0.4892.0> 0956f46d80 10.0.0.193:5984 10.132.0.10 undefined GET /_up 200 ok 0

However the app-service is still dead, and errors with the same error, even when restarted.

To Reproduce Install budibase helm chart with ingress set to false.

Expected behavior

Working budibase service that is not accessible externally without port forwarding.
