Fix crash when ending tiling drag

If the container being dragged has a parent that needs to be reaped, it
must be reaped after we've reinserted the dragging container into the
tree. During reaping, handle_seat_node_destroy tries to refocus the
dragging container which isn't possible while it's detached.
