This function should almost never be called. It clears the tree_model_sort
of any cached iterators that haven’t been reffed with
TreeModel.refNode. This might be useful if the child model being
sorted is static (and doesn’t change often) and there has been a lot of
unreffed access to nodes. As a side effect of this function, all unreffed
iters will be invalid.
