Picking now only happens on allocated actors, but the callback in the actor-pick test is not waiting for the stage to run an allocation cycle. Ideally, we'd wait for this cycle, but for now, forcing an allocation works as well. Allocate the overlay actor in the actor-pick test. https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/1169 (cherry picked from commit 7f488e3e1d13f54ff1bbc9b43ee64cd2dfa82905)
