ElasticContentSaveHook.php: Typecast nessecary

function processDatamap_afterDatabaseOperations

param $id is declared as string but under some circumstances the function gets called with $id as an int. Thus in line 78:
if (strpos($id, 'NEW') !== false) {
$id should be cast to string to avoid exceptions.

Then again in line 81
$currentRecord = $this->typo3Services->backendUtilityGetRecord($table, $id);
$id should be cast to int as the called method expects $id to be int.
