tdf#129898 Use layer DrawnInSlideshow in edit mode

If 'Mouse pointer as pen' is set in slideshow settings, painting in
slideshow becomes persistent. A layer DrawnInSlideshow is created
for that purpose during slideshow. But that layer was not known to
the view from where the slideshow was started.
Generating a layer had been done regardless whether such layer
already exists or not. That had produced several layers with
identical name. That may not happen, because layers are identified
by name.
