If EntityTermsView::getEntityTermsForLanguageListView is asked to output terms for a language but there is no label or description in that language available, it shows a placeholder message. That message is not necessarily in the language terms were requested to be in, but in the UI language. As such, the message needs to be marked with lang and dir attributes. JS already does this, PHP doesn't.
