Description

Certain exception types, for example ActiveMQRemoteDisconnectException are showing the following exception trace when thrown:

org.apache.activemq.artemis.api.core.ActiveMQRemoteDisconnectException: null
	at org.apache.activemq.artemis.core.remoting.server.impl.RemotingServiceImpl.connectionDestroyed(RemotingServiceImpl.java:600) ~[classes/:?]
	at org.apache.activemq.artemis.core.remoting.impl.invm.InVMAcceptor$Listener.connectionDestroyed(InVMAcceptor.java:296) ~[classes/:?]
	at org.apache.activemq.artemis.core.remoting.impl.invm.InVMConnection.internalClose(InVMConnection.java:157) ~[classes/:?]
	at org.apache.activemq.artemis.core.remoting.impl.invm.InVMConnection.disconnect(InVMConnection.java:166) ~[classes/:?]
	at org.apache.activemq.artemis.core.remoting.impl.invm.InVMAcceptor.disconnect(InVMAcceptor.java:246) ~[classes/:?]
	at org.apache.activemq.artemis.core.remoting.impl.invm.InVMConnector$Listener.connectionDestroyed(InVMConnector.java:274) ~[classes/:?]
	at org.apache.activemq.artemis.core.remoting.impl.invm.InVMConnection.internalClose(InVMConnection.java:157) ~[classes/:?]
	at org.apache.activemq.artemis.core.remoting.impl.invm.InVMConnection.close(InVMConnection.java:145) ~[classes/:?]

It would be more aesthetically if they were providing "" as a description instead of "null"

This caught my attention on logs as I thought it was a NullPointerException.

This is just a trivial change.
