Error: [vuex] do not mutate vuex store state outside mutation handlers.

[MathieuDerelle]

it happens in a tree with at least 3 levels

when moving node "test" into "test 2" (as a child)

the stacktrace points to this line https://github.com/suusan2go/vuetify-draggable-treeview/blob/21762258ef51eb4731916cd83c8037af24293ad7/src/DraggableTreeviewNode.vue#L140

which tells me that that array children is not cloned

I am also experiencing this issue when the tree gets to level 3 or more.
