TranslationLanguageRenderer adds langcode field to query even if corresponding value field is not added

Have not yet reviewed

But fix seemed to cause some failures.

Also will need it's own test case.

Should also try and aim for 11.x as that's the current development branch.

prudloff → changed the visibility of the branch 3362917-translationlanguagerenderer-adds-langcode to hidden.

Calling $this->getEntityFieldRenderer()->query() seems necessary because it does not only add the GROUP BY, it also adds the langcode in SELECT so the entity can be rendered in the correct language.

And I can't reproduce the duplicate problem from the issue summary so I'm closing this.
I'll reopen if I manage to reproduce.

I managed to reproduce my original duplicate problem and I think 🐛 Views entity reference relationships must join on langcode for translatable entities Needs review would be the correct way to fix this.
