Evgenii Stratonikov 6ace2f597e [#1234] pilorama: Add test for duplicate directory behaviour
When AddByPath() is called concurrently on 2 different nodes,
internal path components may be created twice. This violates some
of our assumptions in GetByPath() and, indirectly, in S3 handling of
GetSubTree() results.

Add a test for the correct behaviour, fixes will follow.
