[Chiuso] _wpml_jobs_not_notified option is huge

Background of the issue:
We are profiling our requests and trying to understand why some of them simply take too long.

We noticed that the value of `_wpml_jobs_not_notified` option is around 2.6MB

We also noticed that this option is set to `autoload`.

So 2.6MB is loading in every request. Also, we noticed that the WP internal cache is frequently being asked to write the `alloptions` in the cache with this huge size.

We kindly require the following guidance:

Symptoms:
The `_wpml_jobs_not_notified` option is large (2.6MB) and set to autoload, impacting request performance.

Questions:
1) what is this option used for
2) we are not using the feature of translation jobs
3) how can we disable this feature altogether?
4) is it safe to set `_wpml_jobs_not_notified` to `autoload` false?
