Change XAConnectionFactory to extend ConnectionFactory

JMS 1.1, includes the following three interface definitions:

```
public interface XATopicConnectionFactory extends XAConnectionFactory, TopicConnectionFactory

public interface XAQueueConnectionFactory extends XAConnectionFactory, QueueConnectionFactory

public interface XAConnectionFactory
```

why does XAConnectionFactory not extend ConnectionFactory? This is inconsistent.

Please consider changing XAConnectionFactory to extend ConnectionFactory.
#### Affected Versions
[1.1]

Start by locating the Java declarations for XAConnectionFactory, XATopicConnectionFactory, XAQueueConnectionFactory, and ConnectionFactory in this repository, then compare them with the JMS 1.1 definitions quoted in the issue. Review the compatibility implications of the proposed inheritance and existing tests; done means the interfaces consistently reflect the intended relationship and the relevant checks pass.
