Progress bar inconsistency

Summary

The value of the objective function can be not consistent with the value of the objective function in the current iteration.

Gemseo version

gemseo develop

Platform info

Windows/linux

Steps to reproduce

run an optimization problem with a solver computing and storing the gradient of the objective function before the objective function itself.

What is the current bug behavior?

The progress bar is not consistent with the value of the objective function at the current iteration.

What is the expected correct behavior?

The progress bar objective function value should be consistent with the value of the objective function at a given iteration.

Possible fixes

The problem come from the logic implemented in the database for calling the notify_newiter_listeners method in the database: See line 626 of database.py What happens in the copied log is that the notify_newiter_listeners method is called at line 636 when the jacobian of the objective function is stored but before the storage of the objective function itself.
