Describe the bug:
The common.yaml file produced by the spk-reconcile process is missing the service name. The image below shows the result of a pull request produced by the lifecycle pipeline.

The code here seems to be the issue. We should check for empty values before we concatenate most likely.

I suspect this might be an issue with the fact that the bedrock.yaml only contains a displayName and an empty k8sBackend:

rings:
  master:
    isDefault: true
services:
  ./:
    displayName: quick-start-app
    helm:
      chart:
        accessTokenVariable: ACCESS_TOKEN_SECRET
        branch: master
        git: 'https://dev.azure.com/abrig/BedrockRocks/_git/quick-start-helm'
        path: quick-start-app/chart
    k8sBackend: ''
    k8sBackendPort: 0
    middlewares: []
    pathPrefix: ''
    pathPrefixMajorVersion: ''
variableGroups:
  - quick-start-vg

To Reproduce:

Expected behavior:
I should have a valid service name in common.yaml

Does this require updates to documentation?:
