Bug Description

When copying webhook triggers, or when manually assigning the same path to multiple webhooks, n8n arbitrarily selects one webhook and ignores the others.

To Reproduce

1. Add Webhook trigger
2. Copy/duplicate Webhook trigger
3. Execute workflow and call the webhook url
4. One of the triggers is used, the other ignored.

Expected behavior

Error that there are multiple webhook triggers using the same path.
