ISPN-2884 - Upgrade to JGroups 3.3.0.Beta1
ISPN-2787 NPE after ReplaceCommand

* Add MergeDuringReplaceTest to reproduce the issue.
* Fix one of the ControlledRpcManager.invokeRemotely methods that was ignoring the actual result and was always returning null.
* Minor logging improvements to be able to debug this issue.
* Remove harmfull optimization from RpcManagerImpl.invokeRemotely(Collection<Address> recipients, ReplicableCommand rpcCommand, ResponseMode mode, long timeout, boolean usePriorityQueue, ResponseFilter responseFilter) that was not going remotely and neither threw any exception if the destinations were no longer in cluster and current node was the only member.
ISPN-2881 - org.infinispan.loaders.jdbc.mixed.JdbcMixedCacheStoreTest2 - Cache store tests expect purgeSynchronously to be enabled
 * Added the purgeSynchronously parameter
 * Renamed the Class names so that the maven includes running them in testsuite.
