[TYPO3-core] RFC #15400: Bugfix: IRRE - selected items not removed from selector defined as unique

[Martin Borer]

Hi Stanislas,

Thanks for your updated patch. I've tried it, and it was not working. I 
was not able to add or remove relations from the selector after applying 
your patch.

I've used typo3core_bugfix_15400_typo3_4-4.patch with the current Branch 
10112.

Is there missing something in the patch?
