[irybachok]

1. Go to the /#Category/listTree page
2. Drag the first root category in the list to the end, so that it is still a root category - https://screen.treotest.com/i.rybachok/2019-09-20_14-32-04.jpg

Actual result: When dragging the root categories in the “list Tree”, an error in the console is displayed - https://screen.treotest.com/i.rybachok/2019-09-20_14-32-24.jpg

Expected result: There are no errors in the console
