message: [now-cli] Fix inspector url with custom domain suffix
  When the user is using custom domain suffix, the inspector url is a bit different:
  ```
  https://zeit.co/{orgSlug}/{projectName}/{deploymentShortId}/{suffix}
  ```
  This PR adds the necessary logic when constructing the inspector url.
