Validate IncidentUpdate's incident_type field against the retrieved incident type.

[metroid-samus]

The IncidentUpdate's incident_type field is an IncidentTypeBase, which does not have an id field. Thus, the initial id comparison resulted in an error.

However, earlier in the incident_service.update() function call, the incident_type is already retrieved. We can perform the comparisons against this object's id.

I believe the error occurs on incident_in as well:

  File "/Users/wshel/Projects/dispatch/src/dispatch/incident/service.py", line 369, in update
    if incident_in.incident_type.id != incident_type.id:
       ^^^^^^^^^^^^^^^^^^^^^^^^^^^^
AttributeError: 'IncidentTypeBase' object has no attribute 'id'

This works for me locally:

    # Update total incident reponse cost if incident type has changed.
    if incident_type.id != incident.incident_type.id:
        incident_cost_service.update_incident_response_cost(
            incident_id=incident.id, db_session=db_session
        )
