rewrote combox.events.NodeDirMonitor.on_moved method.

   - Now the node monitor waits for all shards of the file, which was
     moved/renamed on a remote computer, to get moved/renamed on this
     computer, before it finally reconstructs the moved/renamed file
     in the combox directory on this computer.

   - Updated the tests for on_moved method at
     tests.events_test.TestEvents.test_NDM_onmoved method.
