adapter method ignores the parameter

The method should return a MessageListenerAdapter wrapping the Reciever
that was passed in. Instead it was creating a new instance. Now it uses
the one it was given.
It looks like this bug crept in 24 days ago when the method was rewritten in [this commit] (https://github.com/fisco-unimatic/gs-messaging-jms/commit/21a13fdab97ae7e357fb30adb9a294fa6c593325).
