Disable failing graphsync test. #110

[juliangruber]

For #110

Unbreak the test suite by disabling the failing test.

@bajtos what do you advise here? Shall we find another provider (if so, how? The top SP from the RSR list?), or keep this test disabled?

I think it's important to re-enable this test. Otherwise, Graphsync retrievals can silently break, and we won't notice until an SP complains about their RSR dropping to zero.

You can look at the top SPs on our dashboard, maybe find one with low HTTP-RSR but high RSR - that means they are serving Graphsync retrievals.

You can find payload CIDs stored with them by manually querying spark-api's eligible_deals table.

I have had an idea how to make it easier to sample payload CIDs for a given miner, but never found time to implement it: Enhance the endpoint returning a summary of eligible deals to also return a random sample of payload CIDs. See
