> While testing creation of intermediate caches for M/R tasks I noticed that remove command fails with CacheException and NPE if the cache has not been created on all nodes. 
> The culprit is in RemoteCommandsFactory where the following line of code:
> registry.getNamedComponentRegistry(cacheName).getComponent(PersistenceManager.class)
> assumes that component with cacheName has been registered.
