When a xdg-toplevel is reset, the window and actor are recreated, and all state is cleared. When this happened, we earlied out from the xdg-toplevel commit handler, which would mean that if the client had queued frame callbacks when resetting, they'd be left in the pending commit state, later hitting an assert as they were not handled. Fix this by queuing the frame callbacks no the new actor, so that they are emitted whenever the actor is eventually painted. https://gitlab.gnome.org/GNOME/mutter/issues/240 (cherry picked from commit d791710197205028be40750d6ee4119f2b7f0e26)
