Service#updated_properties

Returns a hash of the properties that have been assigned a new value since last save,
indicating their original values (attr => original value).
ActiveRecord does not provide a mechanism to track changes in serialized keys,
so we need a specific implementation for service properties.
This allows to track changes to properties set with the accessor methods,
but not direct manipulation of properties hash.
