UNICADOworkflow: - delete unnecessary parameter set in initialize_parameter_study.py
This MR will fix the problem that automatically mode_2 (RFD) is selected if running the parameter study mngr.
- behavior: -> in CSD the mngr will reset the aircraft exchange file to the start_CSD file of the project for each new parameter run -> in RFD the mngr will reset the aircraft exchange file to the start_RFD file of the project for each new parameter run
This MR will close issue #17
