Update profile.py to add MEPGenerator().setup_ports when the profile has only one segment (no DumbProfileJoiner called)

When adding a single duct in MEP no ports where attached.
The function create_profiles_from_polyline does not call DumbProfileJoiner (which eventually calls MEPGenerator().setup_ports).
I have added a check so if there is only one segment, the MEPGenerator().setup_ports is called explictily
