Bug(jx-gitops): helmfile resolve won't handle different environment key and namespace

[Joshua S]

namespaceSubDomain won’t be correctly resolved by jx gitops helmfile resolve if environments[$INDEX].key doesn’t match environments[$INDEX].namespace

see the stg-standby environment key for an example

results in this helmfiles/standby/jx-values.yaml

environments:
  - gitKind: github
    gitServer: https://github.com/
    ingress:
      domain: stg.my-org.com
      externalDNS: true
      kind: ingress
      namespaceSubDomain: .
      tls:

        enabled: true
        production: true
        secretName: tls-stg-my-org-com-p
    key: stg
    namespace: stg
    owner: my-org
    promotionStrategy: Never

    ingress:

      tls:

        secretName: tls-stg-my-org-com-p
    key: stg-standby
    namespace: standby

  ingress:

    externalDNS: true
    kind: ingress

    tls:
      email: [e-mail]
      enabled: true
      production: true
      secretName: tls-stg-my-org-com-p

i would expect the rendered jx-values.yaml to look like

  ingress:
    domain: stg.my-org.com
    externalDNS: true
    kind: ingress
    namespaceSubDomain:  -standby.
