ref.onAddListener not triggering for provider.future

[JifScharp]

Describe the bug
I expect ref.watch(provider.future) to trigger the ref.onAddListener. However, it does not appear to be happening. I'm not an expert in Riverpod, so I wasn't sure if watching a future should trigger this, but when debugging I found that listen was still being called?

  @override
  T watch<T>(ProviderListenable<T> listenable) {
    _assertNotOutdated();
    assert(!_debugIsRunningSelector, 'Cannot call ref.watch inside a selector');

    if (listenable is! ProviderBase<T>) {
      final sub = listen<T>(                       <-- was executed
        listenable,
        (prev, value) => _markDependencyChanged(),
        onError: (err, stack) => _markDependencyChanged(),
        onDependencyMayHaveChanged: _markDependencyMayHaveChanged,
      );

      return sub.read(); 
    }

I added ref.watch(provider) without the future, and immediately the callback is triggered.

To Reproduce

• Create a provider that returns a value
• Add an onAddListener callback
• Call the provider using ref.watch(provider.future)
• onAddListener callback is not called

Expected behavior
onAddListener is called

This appears to have been fixed by the recent selectAsync fix. I've added regression tests for it.
