[PP-1] Race condition with locale javascript translation generation

🐛 Stampedes and cold cache performance issues with css/js aggregation Fixed is committed now, but I don't really see how it affect this. I still think this is is a duplicate of 📌 Remove on-demand JavaScript translation parsing and do everything on rebuild Needs work , moving to 'postponed' and to the locale module.

Just wanted to say that we experienced this on a (quite high-traffic) production site today. We saw hundreds of occurences in the logs. With no alternative, we disabled JS aggregation until we have an official solution.
