Describe this PR

What is the problem we're trying to solve

Current TempAccommodationOfficer does not have Id property. We'll be storing the officer details to Person table and need to be able to add the guid from the table to the TempAccommodationOfficer object, so we can link the records together.

What changes have we introduced

1. Add Id property to the TempAccommodationOfficer object
2. Refactor TempAccommodationInfo and TempAccommodationOfficer objects to use standard constructors rather than the .Create pattern used for other domain objects. (Please see item 4. on how the properties are now handled)
3. Fix the issue where the TempAccommodationInfo object had the QueryableTempAccommodationOfficer entity object in it rather than the correct TempAccommodationOfficer domain object
4. Introduce factories for converting TA related QueryableTempAccommodationInfo and QueryableTempAccommodationOfficer entities to domain objects. This is LBH standard pattern and replaces the constructor setup used in the previous implementation
5. Add test coverage for the affected TA objects and factories
6. Remove obsolete model tests
7. [Unrelated] Update code owners to reflect the current structure
