Fix belongsTo where params

Usually when adding to a `foobar.getBla()` a where param
like `foobar.getBla({where: {x: "y"}})` it should extend
the existing where param (`"id": id`) with the additional
where param.
This didn't work for belongsTo associations until now.
Fixing 'identifier' being stored as the raw value of the 'id' rather than being wrapped in an object
