Adding new attributes temporarily does not work (anymore)

[ChristophLeonhardt]

In previous applications of the package, setting the delete parameter of cwbtools::s_attribute_encode() seemed to effect whether the new attribute was added to the corpus permanently or temporarily. This does not seem to be the case (anymore).

LinkTools/R/LTDataset.R

Lines 515 to 519 in 2bd1924

	if (isTRUE(add_temporarily)) {
	delete_param <- TRUE
	} else {
	delete_param <- FALSE
	}

I am not entirely sure why this would work in the first place. It is possible that it never did work. But it could be a useful option if attributes should only be added for a short period of time.
