Fix issue #1620

[torrefatto]

Hi,

I was hit by this, I see these errors in my ingress event logs

Warning  Translate  9m52s (x1702 over 7d7h)  loadbalancer-controller  Translation failed: invalid ingress spec: failed to validate prefix path /api/* due to invalid wildcard; failed to validate prefix path /service/* due to invalid wildcard; failed to validate prefix path /v2/* due to invalid wildcard; failed to validate prefix path /chartrepo/* due to invalid wildcard; failed to validate prefix path /c/* due to invalid wildcard; failed to validate prefix path /* due to invalid wildcard

I dug a bit and found #1620 and I figured these changes should fix the issue.

What ingress are you using?
