Fix translation of newly added text

[Cathy0123456789]

Description

If a professor continues to type shortly while a translation is being generated, the final saved state of the document may contain an outdated translation that does not reflect the newly added text.

Steps to reproduce:

1. Login as professor
2. Create a job
3. Write a long job description (so translation takes some time)
4. Wait for auto-save so translation is triggered
5. Immediately type something short / paste something, so changes are saved before the translation is done
6. Check the translation, it is of the old text and a new translation is not triggered as well
