What happened? What did you expect to happen?

When submitting workflow, templates are validated and put in status:storedTemplates:

However, there exists a bug that if templates from different templateScope are used but with the same templateName, the later same-name template is not validated.

Our ultimate goal is to have all template validated and put in storeTemplates, so that if a workflow is running, any changes to existing template won't affect the running workflow.

To reproduce the issue load the example to k8s. then run

./dist/argo submit --from workflowtemplate/workflow-template-dag  --dry-run -o yaml

The following are present in storedTemplates

    cluster/workflow-template-print-message/print-message:
    cluster/workflow-template-print-message1/print-message:
    namespaced/workflow-template-dag/hello:

The following are missing in storedTemplates

cluster/workflow-template-print-message1/print-message11:
cluster/workflow-template-print-message1/print-message12:

if we replace template name cluster/workflow-template-print-message1/print-message with cluster/workflow-template-print-message1/print-message1 then all templates appear in storedTemplate
