BuildConfigBuilder does not format out to ImageStreamTagCorrectly

While trying to run the DefaultClientIntegrationTest, it fails against:

oc v1.3.0-alpha.3+6c50f20-dirty
kubernetes v1.3.0+507d3a7
features: Basic-Auth

because of:

com.openshift.restclient.OpenShiftException: Exception trying to POST https://127.0.0.1:8443/oapi/v1/namespaces/int-test-1608/buildconfigs response code: 422 BuildConfig "test" is invalid: spec.output.to.name: Invalid value: "foo/bar": ImageStreamTag name contains invalid syntax

This field is an ObjectRef which supports a namespace property. Best I can tell is the server accepted it previously even though it was not a valid syntax
