[hist] Chi-square computation in Binned likelihood fits

2

As reported in https://root-forum.cern.ch/t/chi-square-definition-in-root/51083/3, the reported chi-square from `TF1::GetChisquare` and from `FitResult` is not correct. A Neyman chi-square is computed but using also the empty bins. See https://github.com/root-project/root/blob/master/math/mathcore/src/FitResult.cxx#L183 We should...
