genie: change command fails script check

[FreddieAkeroyd]

Found on OSIRIS: g.change(title="something") fails load_script checking - it seems it is expecting all parameters to be specified but they should be optional

load_script('U:\fabrizia\Fab_heating_FWS.py')
Traceback (most recent call last):

acceptance criteria

• load_script is able to load g.change(title="something")
• appropriate load_script test added

Discussed 01:24:07 - in planning 02/10/25
