TestE2EPathfinder::test_10_undesired_link_and_max_path had a rerun

[viniarck]

On today's nightly e2e exec this e2e test had a rerun, it needs to be analyzed and see if either time sleep or any other synchornization is needed before the asserts:

@HeriLFIU, could you help out with this one? If you could investigate and run locally a few times exploring it and finding a solutoin that'd be great. Thanks.
