AMQP-395 Restore Exception Logging

JIRA: https://jira.spring.io/browse/AMQP-395

Adding a default error handler (to allow conversion
to a reject and don't requeue exception when there
is a conversion error) suppressed the WARN log
when the listener threw an exception.

Restore the log by logging in the default error handler.
