* Fix failure in IFMapGraphWalkerTest.VrsubConfig and remove it from the flaky list. The data-file was creating a link first and then the nodes. In some runs, the parser and server-table would process all of it and the exporter would get only one trigger per node. But, in some runs, the exporter would get a trigger after the server-table had finished the link processing but not finished the node processing. So, this would cause the nodes to be sent twice to the agent, once without properties (link-create created empty nodes) and the second time with the properties. This would cause the test to fail on counts. Changing the data-file so that the link gets creates last solves this problem and we are still able to make exact checks in the test.
