Erik Grinaker e1a1395cf4 consensus: don't check InitChain app hash vs genesis app hash, replace it (#5237) 
Followup from #5227. Instead of checking `ResponseInitChain.app_hash` against the genesis doc app hash, we instead replace it. We should probably remove the genesis doc app hash completely, and rely solely on the one from `InitChain`, I'll open a separate issue to discuss this.
