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.
