fix: missing default parameters in smash config

[gsprochette]

Description

This PR fixes a legacy related bug where loading a saved SmashConfig with missing hyperparameters for an algorithm (e.g. target modules for hqq_diffusers) would result in an error from the load_from_json function stating that the hyperparameter is missing.

This was due to a discrepency between parent/children hyperparameter coverage between SMASH_SPACE's get_degault_configuration and Configurations's values argument.
