Cluster_test.go panics for nginx deployment

[ppxl]

Originally the test worked out but somehow the nginx deployment no longer works and panics.

The main reason is most probably that something goes wrong during the nginx deployment.

Please fix 😃

That would be this line, podList is definitely empty.

	events, err := cl.Lookout(t).Pod(cluster.DefaultNamespace, podList.Items[0].Name).Events(ctx)

This also didn't workout with a time-out of two minutes ⏳
