Description

Fixes automatic translations not updating the UI upon start and upon receiving the translation response successfully.

Notes

This was introduced in #5059 and (of course) I introduced it. That PR was implementing better UX for translations, mimicking the previous PR that was doing the same thing for transcripts. I missed this one line, sorry 💔

Reproduction steps:

1. Go to NLP/Processing view (through Project --> Data --> Table, in audio question response, "Open" button)
2. Make some transcript (might be done in manual way), e.g. English text "Hello, World!"
3. Go to "Translations" tab
4. Make an automated translation:

• Use "Begin" button
• Select a language, e.g. French
• Use "automatic" button

5. Now you will see a bug:

• Actual behavior: the UI becomes disabled, in Network tab you can notice the API call starts and finishes, the UI doesn't update
• Expected behavior: the UI becomes disabled, in Network tab you can notice the API call starts, UI switches to a spinner with some info, API call finishes, the UI switches to the editor
