Dispose is called before async command finishes executing

[Sibusten]

The implementation of AppRunner.OnRunCompleted does not await next, causing the event to be fired before the async command finishes executing. This causes Dispose to be invoked early.

private Task<int> OnRunCompleted(CommandContext context, ExecutionDelegate next)
{
    var result = next(context);
    context.AppConfig.OnRunCompleted?.Invoke(new OnRunCompletedEventArgs(context));
    return result;
}

Thanks for filing this @Sibusten. I'll look into it this week. If you need this immediately, I'll happily accept a PR with tests.

this is resolved with https://www.nuget.org/packages/CommandDotNet/7.0.3. Thanks for reporting and helping with the tests.
