[Bug]: A new instance of external approval is always created when a ticket is initiated

[smallsheeeep]

ODC version

4.2.0

OB version

Regardless of OB version

What happened?

When a ticket is initiated, a new instance of external approval is always created, even though the approval node list contains no external approval node.

What did you expect to happen?

External approval instance should be created only when a external approval node is needed.

How can we reproduce it (as minimally and precisely as possible)?

1. Config external approval integration;
2. Start a ticket in which the approval node list does not contain external approval;
3. Check the external approval system, you will find a new instance is created.

Anything else we need to know?
