[BUGFIX] Make translating inline elements possible

[BUGFIX] Make translating inline elements possible

If a translated parent record has inline childs its
now possible to translate new childs of the translation
parent of parent record.

For example if a tt_content element has new images
added to the default language its now possible to add
the translation for the image reference in the
translated content element.
