QPID-7077: [Java Client] Remove temporary logging

> [Java Client] NPE reported from failover handling code

>                 Key: QPID-7077
>                 URL: https://issues.apache.org/jira/browse/QPID-7077
>             Project: Qpid
>          Issue Type: Bug
>          Components: Java Client
>    Affects Versions: qpid-java-6.1
>            Reporter: Keith Wall
> The CI logs for AddressBasedFailoverBehaviour showed a NPE within failover handling code.
In this case, the NPE cause the IO thread to abort (it was caught by the uncaught exception
handler and log.  A test failure was not reported.
> This problem could only affect a user using the connection failover feature. If this
problem were to occur in a user application, I think the affect would be that the application
would not auto reconnect.  This could affect the resilience of a user application.
