The forms export process does not include all answers if the user language is Basque.

Steps to reproduce

1. Define the languages properties for this test with locales.enabled=eu_ES,en_US,es_ES in portal-ext.properties
2. Create a site X with Spanish as the default language
3. Create a new form F in X
   1. Add a Spanish localization to the form F
   2. Add a Basque localization to the form F
4. Create a new page P1 in site X
5. Add to P1 a Form widget where the form F is shown.
6. Add to P1 a Language selector widget
7. Fill the form and submit in the three different languages: Spanish, Basque and English, using the Language Selector to change the language
8. Go to the Form administration screen
9. Change the site language to Basque (add /eu before the /group part in the URL or change the language of your user)
10. Next to the form F, use the ⋮menu to choose "Esportatu" (Export) option
11. Export the form entries in CSV (click on the blue button Onartu)

Expected behaviour

A file with all the form entries will be generated.

Actual behaviour

A file with all the form entries except those created when the English locale was chosen.

additional notes:

I tried with other beta languages but I was unable to reproduce it.
