ABP vnext 种子文件更新

需要在 HttpApi.Host 的OnApplicationInitialization方法下配置

 AsyncHelper.RunSync(async () =>
            {
                using (var scope = context.ServiceProvider.CreateScope())
                {
                    await scope.ServiceProvider
                        .GetRequiredService<IDataSeeder>()
                        .SeedAsync();
                }
            });
