Don't remove Element on destroy() #26
Description
Line 261 in 3334451
When calling destroy(), the Element where the graph is being applied is removed from the DOM. Since this element is not created and managed by p2p-graph but instead provided by us, it should be left untouched, as it's done at https://github.com/Novage/p2p-media-loader/blob/85adce9b0edbc00dfa073321d93a61590af3afc8/p2p-media-loader-demo/index.html#L1234-L1240
