chore(jssp): disable population diversity estimation (#428)

<!-- If applicable - remember to add the PR to the EA Rust project (ONLY
IF THERE IS NO LINKED ISSUE) -->

## Description

Right now this mechanism is either not working or the solver is really
bad.
This needs to be tested, however using this right now is pointless.
