Http provider bug after import

When I import the following flow, the link between the http provider component and its linked response component is lost.

[ics to Transiscope en pays nantais_backup.json](https://github.com/user-attachments/files/20739348/ics.to.Transiscope.en.pays.nantais_backup.json)

Hypothesis : new components id are created when importing but the response component id of imported http provider is not updated

Start with the attached `ics to Transiscope en pays nantais_backup.json` flow and trace the import path for HTTP provider and linked response components. Compare component IDs before and after import; done means the imported HTTP provider still points to its response component.
