tests/interactive: Remove clutter paint-wrapper test
The paint-wrapper test wraps around the painting process of an actor to paint its own texture before and after painting, it does that using the "paint" signal. This signal is deprecated and will be removed from Clutter, and since this "use-case" won't be supported anymore afterwards (the proper way is to use a ClutterEffect for things like this), remove the test. https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/1522
