This removes the last creation of foreground tasks in the compilation
state. I think this logic can be removed completely, because
a) the number of background tasks is already capped at {max(1,
FLAG_wasm_num_compilation_tasks)}, and
b) in order to get predictable timing you can use the --predictable
flag which makes all background tasks execute synchronously with
foreground tasks (from the same queue).
