Georges Basile Stavracas Neto 99b78d3ee8 Revert "appDisplay/baseAppView: Cleanup animate()"
This reverts commit cd8269185. It turns out this seemingly
harmless cleanup introduced a regression:

 * Open overview
 * Press Meta+A twice
 * Close overview
 * Press Meta+A
 * Enjoy an invisible grid

Fixes https://gitlab.gnome.org/GNOME/gnome-shell/-/issues/3451
