Bug in serialisation of minimizer fit report objects

[SpaceMan013]

Unpickling stage fails for the minimizer fit reports generated by a script while with a notebook with interactive progressbar there are no problems. Likely cause is the progressbar behaving differently on jupyter notebooks and python scripts. (See slack discussion)
