When a node has a layout override, the translation from the layout library is not being applied

Problem/Motivation

After creating a translation of the node, the layout library translation is being applied properly. However, when a node layout is being overridden, the translation of the layout is not being applied from layout library anymore.

Steps to reproduce

- Add a translation to layout library
- Create a node a select the layout from the library
- Add a translation to the node. At this point the layout library translation is being applied, which is correct.
- Go back to the original language
- Click on Layout
- Save the layout (don't need to do any change)
- Go to the translation of the node
- The configuration translations, such as the block titles, are now using the values from the original language, instead of using the translated values from the layout library translation.
