Filer - Update change of registration filing processor to work with alternate name changes - Part2

This ticket was created to handle the issue found in #20328

When I tested change of registration filing processor using the filing submitted by UI for FM0555069(GP), where filing id is 555576 for reference, it throws PendingRollbackError.
```
"This Session's transaction has been rolled back due to a previous exception during flush.
To begin a new transaction with this Session, first issue Session.rollback(). Original exception was: "
```
After diving into it a bit, the issue is probably on accessing [entity_delivery_address/entity_mailing_address](https://github.com/bcgov/lear/blob/feature-legal-name/queue_services/entity-filer/src/entity_filer/filing_processors/filing_components/parties.py#L161-L164) The error message I got is shown as follows.

Need to test other firm scenarios as well to see if there're similar issues.
