Update git submodules

* Update plugins/replication from branch 'master'
  to 012f04240eafe6dfa21fd94e012e97498881c621
  - Remove remaining event posting from synchronized sections
    
    Posting events sometimes can take significant time, mainly due to the
    event visibility checks. When this is done from a synchronized block
    then all other threads trying to schedule replication to the same
    (locked) Destination get blocked. Even worse, the synchronization
    happens on the Destination level, so even operations on unrelated
    repositories block each other.
