MappedObject does opposite of what it says it does

Problem/Motivation

The code does the opposite of what it says it does

salesforce/modules/salesforce_mapping/src/Entity/MappedObject.php

// If $value is TypedData, it should have been set during pullValue().
if (!$value instanceof TypedDataInterface) {
  $drupal_field = $field->get('drupal_field_value');
  $drupal_entity->set($drupal_field, $value);
}

Proposed resolution

Remove negative validation.
