Missing chunks for distant validators

[staffik]

Creating a statelessnet cluster with 2 validators in distant locations, e.g.

    validator0      = "southamerica-east1"
    validator1      = "asia-northeast1"

demonstrates there are a lot of missing chunks, even without any transactions. That needs investigation and fixing it.

I assume @saketh-are is taking care of this now :)
