delete option of lookup does not work with arrays and do list-bind

I forgot to open a ticket for this I think. Now I had the same problem again.

It seems that the delete option is not working if one is trying to lookup in another array while iterating with a do list-Bind.

Had another altercation with a problem of the delete option: hbz/lobid-resources@b54b8af

The delete option created an label, that should not be there. If I delete the delete option, the unwanted label is deleted again.

This also seems to be happening if I use delete in the same array with do list:

do list(path:"@hochschulfaechersystematik","var":"$i")
  lookup("$i","tuDelftSubjects2destatis", delete:"true")
end
