[Pillar II ESM] Review why sometimes COMPSs jobs logs are not present in the .COMPSs folder

[kinow]

@rohanali1798 and I noticed that sometimes the folder that we give to enqueue_compss, does not contain all jobs.

Especially when we were testing pruning, while the task ran, and when it failed, sometimes we had job1, job2. But in the tmp.$random-string? folder there were job1, job2, job3 files.
