TYPO3 Core

I appended a patch. I think it was just a small logic error. Hopefully I'm not totally wrong. :)

How to reproduce?

1. Create a TCA with an inline column. Both of them needs to use multilanguage settings.
2. The inline column needs to use the MM table configuration
3. Create some test records and localize them.
4. Go to the parent TCA in the default language.

Result:
You will see, that the localized records are shown within the default language with the default record under it in the inline element list. If you switch to the translation of the parent TCA, then you will see, that the records are missing, or shown as "not translated".
