Drop event thrown for no change

[pndewit]

Using your example project: https://github.com/michaelmalonenz/aurelia-dragula-example

1. Add a breakpoint, console log, or anything else to notify you (that it has been triggered) on line 32 in welcome.js (so just inside the drop function)
2. Start it up and submit the name: "test"
3. Note that the repeater DOM ends with a <!--anchor--> node (after the last <compose> element)
4. Move the last (right) letter, but do not actually change its position in the list. Just drag it, move it a px or 2 to initiate the drag and release it again.

The drop event should now have fired! Like I said this is because the _initialSibling is set to the <!--anchor--> from step 3 which is then compared to the _currentSibling which is set to null. They are obviously not equal, triggering the drop event.
