Title: `_cached_children` attribute is list, expecting a queryset

The template filter cache_tree_children ends up caching the children as a list, and subsequent calls to get_children() returns this cached list. Therefore any code that expects a queryset from get_children() will succeed before and fail after.

Not sure if a kwarg is an ideal solution, but I thought the list behavior was a bit odd to start with.
