@PreDestroy method not awaited
## Quarkus version

2.14.2 on Linux with OpenJSD 11.0.17+8


## Actual behaviour

I get the following exception on session timeout:

```
ERROR [io.qua.arc.imp.AbstractInstanceHandle] (executor-thread-31) Error occurred while destroying instance of bean 
[...SessionManager_Bean]: javax.enterprise.context.ContextNotActiveException: SessionScoped context was not active when trying to obtain a bean instance for a client proxy of CLASS bean [class=...MyAPIClient, id=5b2...]
```


## Expected behavior

Session scope and @SessionScoped beans should not be destroyed as long as all methods annotated with @PreDestroy of unremovable beans have returned.


## How to Reproduce?

```java
@Named("myAPIClient")
@SessionScoped
public class MyAPIClient implements Serializable {

...

}


@Named("sessionManager")
@SessionScoped
public class SessionManager implements Serializable {

	@Inject
	private myAPIClient myAPIClient;

	@PreDestroy
	public void autoLogout() {

		myAPIClient.doSomething();		// <-- Exception thrown here
		
	}
	
	...

}
```

Any hints?
