Changes toolAggregate to allow for but remove empty mapping targets

[codeZeilen]

Open questions:

• To which degree do we want to handle "weird" mapping relations (e.g. data frame that contains NULL, which is not trivial to achieve in the first place)

TODOs:

• run pipeline with the change
• should we add a note that there were empty cells, which will be ignored in the output?

I think a note would be indeed useful.

Something is off. I have already implemented the note but it is not in there. Will go looking for it.

Found the missing commit, will squash on merge to remove the weird history.

looks good. Just as a side note: you could probably write lines 506 - 512 more compact using the dim argument in magclass objects, e.g. something like m <- m[emptyValues, dim = i, invert = TRUE]

Ah, perfect, I was looking for something like this, but was not aware of that!

Also: This is such a convoluted PR commit log for such a small code change 😄
