QueueAttribute not being persisted in database

Nobody has claimed this yet.

Hi,
**_Setup:_**
Version of **Hangfire.Core 1.7.12**
Storage package: **Hangfire.PostgreSql 1.7.1**
**.net core 3.1**

I'm using the QueueAttribute as explained in the [DOCS](https://docs.hangfire.io/en/latest/background-processing/configuring-queues.html?highlight=queue)

And the worker is working correctly, picking up the correct job.

```
public interface IMyJob
{
[Queue("myQueue")]
Task ExecuteAsync(CancellationToken cancellationToken);
}
```

```
services.AddHangfireServer(options =>
{
options.Queues = new[] { "myQueue" };
});

```
```
recurringJobManager.AddOrUpdate(
"myjob",
job => job.ExecuteAsync(CancellationToken.None),
"*/1 * * * *")
```

However, the queue is not correctly persisted in the DB (it is persisting as Queue = `default` in the `hash` postgres table)

I can only solve that when I explicitly specify the queue name in the `AddOrUpdate` method:
```
recurringJobManager.AddOrUpdate(
"myjob",
job => job.ExecuteAsync(CancellationToken.None),
"*/1 * * * *",
"myQueue");
```

Is this normal behavior, or something I'm missing?

Start by reproducing the shown IMyJob interface and recurringJobManager.AddOrUpdate calls with Hangfire.Core 1.7.12 and Hangfire.PostgreSql 1.7.1. Inspect the resulting Queue value in the PostgreSQL hash table and compare the attribute-based call with the overload that explicitly supplies myQueue. Done means the attribute behavior is explained and, if incorrect, the queue is persisted without requiring the explicit argument.
