Fix system tests performance.

Summary

After the refactoring of the archive/retrieve test some performance regression where introduced mainly related to the inclusion of a sqlite db to track the progress. Also, the refactoring does not allow to run several tests at the same time.

What is the expected correct behaviour?

• Be able to run multiple tests at the same time.
• Do the db update on the background // somewhere else to avoid the stall.
