Recreate deprovidioned users on login

[phavekes]

When a user had been deprovisioned trough the lifecycle API, he might return later, and get the same collabpersonID.
At the moment, this causes an error:

{"message":"Exception occurred while processing command \"Surfnet\\StepupMiddleware\\CommandHandlingBundle\\Identity\\Command\\UpdateIdentityCommand[e4731040-7b60-40d4-aca9-634861466db8]\": \"Operation on this Identity is not allowed: it has been forgotten\", rolling back transaction","context":{"exception":{"class":"Surfnet\\Stepup\\Exception\\DomainException","message":"Operation on this Identity is not allowed: it has been forgotten","code":0,"file":"/var/www/html/src/Surfnet/Stepup/Identity/Identity.php:1446"}},"level":400,"level_name":"ERROR","channel":"app","datetime":"2025-01-23T15:18:54+01:00","extra":{"art":"24787","server":"middleware.test2.surfconext.nl","application":"middleware","request_id":"8bffc46f51882904a0f39a71d9d6e54b"}}

If a user returns after being forgotten, we should recreate the user as if it was a new user.
