tsh apps config -F uri returns wrong uri

[tstenner]

tsh apps config $app -F uri returns an URI below the leaf cluster domain instead of the root cluster domain.
tsh apps login $app returns the correct uri:

$ tsh apps login $app
Logged into app $app. Example curl command:

curl \
  --cert "…" \
  --key "…" \
  https://$app.$root_domain

$ tsh apps config revolut-svc-gsit-opensearch-cluster -f curl
curl \
  --cert "…" \
  --key "…" \
  https://$app.$leaf_domain
