Cleanup: remove automatic parameter from unload_filament() 

In M600 and M702, the Z-lift is taken care of outside this function
so it makes no sense to have a Z-lift within unload_filament()

Only exception to this is in the wizard, there I moved the Z-lift to
happen before we start heating the nozzle.
