che: Can't use custom registries

Describe the bug

I have a problem trying to use custom devfile and custom plugin registry. I can build and deploy them without any errors or problems, but the changes I made don’t show up. Neither the custom Stack from the devfile registry nor the added plugin of the plugin registry. To build the registries I use the build.sh, which is contained in the registries repos. To deploy I use:

NAMESPACE="kube-che"
DOMAIN="$(minikube ip).nip.io"
helm upgrade --install che-plugin-registry \
    --debug \
    --namespace ${NAMESPACE} \
    --set global.ingressDomain=${DOMAIN} \
    ./kubernetes/che-plugin-registry/

for the plugin registry and:

NAMESPACE="kube-che"
DOMAIN="$(minikube ip).nip.io"
helm upgrade --install che-devfile-registry \
    --debug \
    --namespace ${NAMESPACE} \
    --set global.ingressDomain=${DOMAIN} \
    ./deploy/kubernetes/che-devfile-registry/

for the devfile registry.
