PdTest.FUNC_SynchronisationAndPruning fails about maidsafe HOT 2 CLOSED

Surprisingly the test occasionally passes.

from maidsafe.

The reason of failing is :
During Pruning (vault::Node::PerformMaintenance() ),
only prev_close_nodes_ (which is fixed to 8 ) will be passed on to account_handler_ or chunk_info_handler to check
if the current node is among the k-closest to the holding chunk.
If the holding chunk is far away from the current node (i.e. many nodes got joined after the current node held the copy of the chunk), then the current node won't know all that chunk's k-closest in its local prev_close_nodes_
This results in the current node think itself is among the k-closest and decide not to remove the chunk.
(which is wrong ! )

A function currently being developed in Routing , something like bool IsInGroup(target_id, current_node_id) , is said to be more accurate and get this problem solved.
