clutter/tests/actor-destroy: Check destroying the actor clears the children

Browse Source 
Commit df7d8e2cb highlights a crash on test_destroy_destroy, in fact it could
happen that calling clutter_actor_destroy on a child while iterating on the
list, would implicitly call test_destroy_remove that tries to modify the list
at the same time. Causing a memory error.

So instead of manually free the children list, just ensure that this list is
valid and that when the object destruction is done, this is free'd.
