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.
I figured the performance would be the same regardless of whether I used a separate KeyFilter or not, but at least this way I only have one anonymous class.
