Avoiding NPE (https://issues.jboss.org/browse/JGRP-1715)
Fixed issue that if a runnable is retrieved from the awaiting queue
before it registers it's requestId that it would throw a NPE.  This
should only happen if there is a task that is cancelled for some reason
else the consumer found responses should match the queue size.

Fixed CME that was thrown because not properly protecting iteration
of SynchronizedHashMap.  Also fixed up issue that when reregistering
a task that we have to add our id first before sending to coordinator.
