fix(NLP): missing suggested language in language selector DEV-17

[magicznyleszek]

💭 Notes

Loop of asynchronous calls was bad. I made Promise.all that fixes the problem.

👀 Preview steps

I can reproduce this on kf.main but I believe this is on production too.

1. Create a form with one audio question
2. Create two submissions (each with one audio file)
3. From the data table, click Open for the first submission.
4. Create a manual transcription in English. Save it.
5. Delete the transcript.
6. Go to the second submission (from the data table or by just clicking the up/down button from the same screen).
7. Create a manual transcription in Spanish. Save it.
8. Go back to the first subscription. Try to create a new transcript in English.

Expected behavior: The top of the language list shows English in the first position.

Instead: English is not displayed at all (and can't be found by searching either). Spanish is displayed in first position.
