Fix #1020

[cthoyt]

Should we be handling the reduction type anywhere else?

[mberr]

There is already some handling inside the loss functions, e.g., here

pykeen/src/pykeen/losses.py

Lines 839 to 840 in b0a9abd

	if self.reduction == "sum":
	positive_loss = positive_loss * negative_scores.shape[1]

I am not aware of any other location where we should need to look at the reduction, and don't do it yet.
