operator-sdk: Test fails with no matches for kind \"Route\" although routev1 is added to schema

Bug Report

What did you do?

I am following the code skeleton for writing test for controllers

Since my controller also uses openshift routes I added the route to the schema

//controllers/suite_test.go
import (
       ...
	routev1 "github.com/openshift/api/route/v1"
	"k8s.io/client-go/kubernetes/scheme"
	...
)

func TestAPIs(t *testing.T) {
	RegisterFailHandler(Fail)
	RunSpecsWithDefaultAndCustomReporters(t,
		"Controller Suite",
		[]Reporter{printer.NewlineReporter{}})
}

var _ = BeforeSuite(func(done Done) {
	logf.SetLogger(zap.LoggerTo(GinkgoWriter, true))

	By("bootstrapping test environment")
	testEnv = &envtest.Environment{
		CRDDirectoryPaths: []string{filepath.Join("..", "config", "crd", "bases")},
	}

	var err error
	cfg, err = testEnv.Start()
	Expect(err).ToNot(HaveOccurred())
	Expect(cfg).ToNot(BeNil())

	err = elmv1.AddToScheme(scheme.Scheme)
	Expect(err).NotTo(HaveOccurred())
	//ADD ROUTE-V1
	err = routev1.AddToScheme(scheme.Scheme)
	Expect(err).NotTo(HaveOccurred())	


	k8sClient, err = client.New(cfg, client.Options{Scheme: scheme.Scheme})
	Expect(err).ToNot(HaveOccurred())

	k8sManager, err := ctrl.NewManager(cfg, ctrl.Options{
		Scheme: scheme.Scheme,
	})
	Expect(err).ToNot(HaveOccurred())
        
        //try to add route v1 again - does not help 
	err = routev1.AddToScheme(k8sManager.GetScheme())
	Expect(err).NotTo(HaveOccurred())

	err = (&ELMReconciler{
		Client: k8sManager.GetClient(),
		Log:    ctrl.Log.WithName("controllers").WithName("ELM"),
	}).SetupWithManager(k8sManager)
	Expect(err).ToNot(HaveOccurred())

	go func() {
                //this call will fail with no matches for kind Route
		err = k8sManager.Start(ctrl.SetupSignalHandler())
		Expect(err).ToNot(HaveOccurred())
	}()

	k8sClient = k8sManager.GetClient()
	Expect(k8sClient).ToNot(BeNil())

	close(done)
}, 60)

What did you expect to see?

I expected the manager to start in the test suite without errors as it does in runtime

What did you see instead? Under which circumstances?

After manager.start is called the test fails with no matches for kind "Route" error
