Not changed fields in CustomType will be deleted

[guidostoffKt]

Method extractChanges in vendor/bestit/commercetools-odm-1.22.2/src/UnitOfWork/ChangeManager.php also removes fields in the CustomType that have not changed. Commercetools removes these fields, because the CustomType is assigned as a whole. The following lines after line 122 would do the trick for me

if ($key === 'custom' && array_key_exists('fields', $changedSubData)) {
$changedSubData['fields'] = $value['fields'];
}
