TYPO3 Core

i think we should except early in those cases. we should try to add either a new class "TcaSanitize" (or similar) and call it in bootstrap just before "TcaMigration" (and at the other places where TcaMigration is used), or just add a method "sanitizeTcaType()" to TcaMigration class directly (as first method call).
The check should throw an exception, ['config']['type'] is a mandatory field since ever.
