[effects/fallapart] Override scale, fade, and glide effect

Summary:
Currently the fall apart effect doesn't work in conjuction with window
open/close animation effects, e.g. scale. The reason for that is those
effects grab windows before the fall apart effect.

Test Plan:

• Enable the fall apart effect and the scale effect;
• Close a window.

(without this patch the window doesn't fall apart)
