TVB-2736. Enhance Copy simulation use-case
Created by: popaula937
At Copy time:
- fill fields from session for a better user experience
- reset dependent entities (model, noise) if the user changes the Connectivity/Surface
In the current form, it also keeps selected values at NEW simulation config, in case the user uses Previous.
Would help if someone else would also click a bit on the GUI to assess if there are inconsistencies left.
