[IMP] estate: Modify the res.user to add property_ids by inheritance

Overrides ondelete and create method for the models
- on delete for property model
- on create, offer to check if an offer with a higher bid already exists or not

Inherited the res. user to add a new property_id field to it
so that we can list all the properties associated with the User's account.
