ISPN-4291 Poor REPL state transfer performance with cache stores

https://issues.jboss.org/browse/ISPN-4400

* Skip the cache store iteration if the local node didn't lose any segments
* Move the invalidation after receiving the transaction data, so that write
  commands can be performed in parallel.
see my comment above. I still think that it is good. after all, they were added for some reason :)
