Running integration tests with go fails for argocd cli login to the cluster #256
Description
I am not sure if this is a problem with my setup but I can't get the go integration tests to run.

As the kind cluster still lives afterwards I had a look, seems it does not have the argocd-initial-admin-secret inside that the login process relies on.
k -n argocd get secrets
NAME TYPE DATA AGE
argocd-redis Opaque 1 3s
argocd-secret Opaque 0 0s
sh.helm.release.v1.argocd.v1 helm.sh/release.v1 1 56s
When I mnaully retrieve the secret from there with (not sure if this is enough to reproduce what the script does):
export ARGOCD_OPTS="--port-forward --port-forward-namespace=argocd"
argocd login --insecure --username admin --password
I get the same error message as from the integration tests.

Steps to reproduce:
git clone https://github.com/dag-andersen/argocd-diff-preview.git
cd argocd-diff-preview
make run-integration-tests-go

Do I need to consider something before executing the tests?
If not, do you have a hint what could be the issue with my environment.
