title: TCA error in TYPO3 8.6 while adding new items
body: <p>When I want to add new records in TYPO3 8.6 with go_maps_ext, I get the following error:</p>
  
  <pre><code>Argument 3 passed to 
  TYPO3\CMS\Core\DataHandling\Localization\DataMapProcessor::synchronizeTranslationItem() 
  must be of the type integer, null given, called in 
  .../typo3/sysext/core/Classes/DataHandling/Localization/DataMapProcessor.php on line 195
  </code></pre>
  
  <p>The TCA definition can be watched on GitHub <a href="https://github.com/mhirdes/go_maps_ext/blob/master/Configuration/TCA/tx_gomapsext_domain_model_address.php" rel="nofollow noreferrer">https://github.com/mhirdes/go_maps_ext/blob/master/Configuration/TCA/tx_gomapsext_domain_model_address.php</a></p>
  
  <p>It dosen't matter if I want to insert a new map or address. Any suggestions? Thanks a lot in advance.</p>
