Some Portal creation failures incorrectly result in `Succeeded` state

[jameshbarton]

Describe the bug Sometimes when Portal creation fails like in #90 , the Portal CR incorrectly reports its state as Succeeded.

To Reproduce

1. See #90
2. Observe incorrect Succeeded state in Portal CR:

   status:
   observedGeneration: 1
   publishedEnvironments:
   - apiProducts:
     - name: petstore-product
       namespace: default
     name: dev
     namespace: default
   state: Succeeded

Expected behavior A failed Portal creation should have a matching failed status.
