What does this PR do?

Previously, line 192 was causing the following warning:

 UserWarning: To copy construct from a tensor, it is recommended to use sourceTensor.clone().detach() or sourceTensor.clone().detach().requires_grad_(True), rather than torch.tensor(sourceTensor).
  total_n_grams[n] = tensor(sum(n_grams_counts[n].values()))

My changes solves this warning.

It is very strange to me that this simple change to chrf metric results in the BLEUScore metric consistently falling in some CI builds. To my knowledge the two metrics are completely independent of each others.
@stancld do you have a idea what is going on?
