BUG : correct CALATKCommandLineBullseyes Configuration Verification Tests failing

- the Baseline JSON files expected output for LineSearchUnconstrained but the solver was not specified, so it was using the default one : StepLengthSelection, that therefore was using different parameters
- to fix it we only specified the old solver to be used, UnconstrainedLineSearch, but the best would be to create another test sith the new Solver, StepLengthSelection
