Title: JMS Reporter: Avoid javax.management.InstanceAlreadyExistsException when registering.

# JmxReporter

When **Registering a Bean** we check if its *ObjectName* is already registered, if it is we unregister before registering the *ObjectName* again avoiding an `javax.management.InstanceAlreadyExistsException`.
