Added tests for the contents of the search bar language menu

Translations can be maintained with the Symfony-Lokalise combination (pull, push, extract)  but not yet by extracting from Vue code (#1648)

At first, there was some uncertainty about whether the system was actually updating the data correctly (deletion in Lokalise -> deletion locally as well), but it seems that it worked correctly after all. Although the feature branch can be merged, further testing should still be done just to be sure.
