[davepuchyr]

Summary of Bug

Using the "--height" flag on gaiacli query staking validator returns ERROR: {"codespace":"sdk","code":1,"message":"substore proof was nil/empty when it should never be"}.

gaiacli query staking validator cosmosvaloper1rcp29q3hpd246n6qak7jluqep4v006cdsc2kkl --chain-id cosmoshub-1 --output json --height 181463
