core: Copy filters for new single-layer images

Browse source 
Resolves #12198.
When dragging a layer to the toolbox to create a new
image, we weren't copying over the filters. This is because
that action still uses gimp_image_new_from_drawable ()
rather than the multi-layer capable gimp_image_new_from_drawables ()
function.
For now, we'll fix the immediate problem by implementing the filter
copy code in this function. Long term, we should port that code to
use gimp_image_new_from_drawables () instead.
