NPE in ArtemisJmsProducer.connectionFactory()
**Describe the bug**
A minimal application using `quarkus-artemis-jms` fails to start with strange NPE. See full code below.

**Expected behavior**
The application should start and initialize JMS ConnectionFactory without any exceptions.

**Actual behavior**
NPE immediately after startup:

**To Reproduce**

Create a project consisting of the following two Java source files and a pom.xml, then run `mvn quarkus:dev`.

```java
import io.quarkus.runtime.StartupEvent;

import javax.enterprise.event.Observes;
import javax.inject.Singleton;

@Singleton
public class Bean1 {

  public void onStart(@Observes StartupEvent ev, Bean2 bean2) {
    bean2.doSomething();
  }
}
```

```java
import javax.enterprise.context.ApplicationScoped;
import javax.inject.Inject;
import javax.jms.ConnectionFactory;

@ApplicationScoped
public class Bean2 {

  private final ConnectionFactory connectionFactory;

  @Inject
  public Bean2(ConnectionFactory connectionFactory) {
    this.connectionFactory = connectionFactory;
  }

  public void doSomething() {
    connectionFactory.createContext();
  }
}
```
