Fix: On woocommerce test ping issued during a webhook creation, retur…

[labeneator]

This PR fixes 2 issues:

1. During the configuration of a woocommerce webhook. An unsigned test ping is issued to erpnext. Erpnext throws a 417 or 500 because of this non JSON payload. This has a detrimental effect of disabling the webhook if the test ping returns a status code > 500 5 times.

• See https://woocommerce.com/document/webhooks/#creating-webhooks
• See Webhook only containing webhook_id as payload woocommerce/woocommerce#15642 (comment)

2. During a new order webhook. Next ERP will attempt to rename the customer if the customer already exists in the system. If the old & new details are the same, an exception is thrown. This PR adds a check to ignore a rename if old == new.

PR resolves #33708
