Drop items are not necessarily deep copied
Issue https://github.com/codef0rmer/angular-dragdrop/issues/143 had been closed, but items still were deep copied even when settings were specifying not to do so.
@damrem Thanks man..! Can you add a unit test?
@codef0rmer Sure! I should find some time soon.
Hey, I've finally added tests.
@damrem Thanks for adding tests. I noticed that the direction animation breaks by not using deepCopy by default in https://github.com/codef0rmer/angular-dragdrop/blob/master/demo/dnd-insertInline.html.
I do not remember If I intentionally left it to be deep copied for animation to work. Did you face any problem with that?
