fix: fix specific params problem with branches

[JoanFM]

Solves an issue with executor specific parameters per Executor.

Original problem is that request is concurrently altered and there are issues on how they are updated before they are sent.

This problem is now solved by deepcopying the request before sending, but we have to analyze if this is the right approach since it can imply performance degradation. To solve this I added some optimizations in the code to detect when it is actually needed

Here I just want to validate this functionality would work, specially if the __results__ handling is correct
