🐞 Description of the bug

When switching on pseudo timestepping with the pb-coupled solver we are losing access to the "mg_controls" object method.

📝 Steps to reproduce

1. launch a fluent solver session with show_gui=False
2. load in any mesh
3. turn pseudo time method OFF via: session.solution.methods.pseudo_time_method.formulation.coupled_solver = "off"
4. show advanced controls: session.solution.controls.advanced()
   this shows that we can modify mg_controls:
   
5. now turn pseudo time method ON via: session.solution.methods.pseudo_time_method.formulation.coupled_solver = "global-time-step"
6. show advanced controls: session.solution.controls.advanced()
   this shows that we no longer have access to mg_controls:
