Steps to reproduce:

• start with clean Ibexa Experience v4.2.3
• create Content as child of  Ibexa Digital Experience Platform > Ibexa Platform
• do not Publish use Publish Later
  (important : choose today and current time - error only occurs when ezplatform:scheduled:run tries to publish the Content Item)
• send folder Ibexa Platform to Trash
• run scheduler command

  php bin/console ezplatform:scheduled:run

Result:

Command throws exception and exits:

Starting publishing scheduled content
Total scheduled for publication: 1
Ready for publication: 1
Processing:
 - "Folder" [2022-11-30T14:02:52+00:00] (id: 59, version: 1)...
In DoctrineDatabase.php line 83:                                         
  Could not find 'location' with identifier '42'  

Expected:

• command should continue processing entries
• orphaned scheduled entry should be removed
