Daniele Sciascia 4ac15e4349 Fix attempt to replicate empty fragments ...

* Adds method wsrep::transaction::streaming_step() so that there is a
  single place where streaming context unit counter is udpated.
  The method also checks that some data has been generated before
  attempting fragment replication.
* Emit a warning if there is an attempt to replicate a fragment and
  there is no data to replicate.
