tests/actor-pick: Allocate actor before picking

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.
