Unable to resolve images in unauthenticated registries

[scothis]

Building an image targeting an unauthenticated registry completed the builds and published the image to the registry, however, the kpack-controller errors when it is unable to find a secret for that registry (there shouldn't be one). This results in the build's ready condition never becoming true.

Here's what I see in the kpack-controller log with v0.0.4. In this case, registry.kube-system.svc.cluster.local is also an insecure registry, but I doubt that's what's causing issues.
