It might happen that the target clutter actor that we return on call of st_texture_cache_load_sliced_image might be destroyed while the loading task is still running. To protect from this, let's connect to "destroy" signal and when this happens we use a cancellable to stop the task. This allows to safely reuse the return value of this function to cancel the execution and avoiding that load_callback is called even for a request that is not anymore under our control. https://bugzilla.gnome.org/show_bug.cgi?id=765011
