Migrate from v0.34.x to v0.36.0 failed to start

[zhangyelong]

The gaiad migrate command updates the staking.validators[].consensus_pubkey to the tendermint pubkey:

"consensus_pubkey": {
     "type": "tendermint/PubKeyEd25519",
     "value": "GAmkUd2U23giBm9sv/B4PswQzGRR12obt6hecDvk8cQ="
},

but actully the bech32 is expected:

"consensus_pubkey": "cosmosvalconspub1zcjduepqrqy6g5wajndhsgsxdaktlurc8mxppnry28tk5xah4p08qwly78zqth7d8n"

This causes the panic: json: cannot unmarshal object into Go value of type string when starting with gaiad v2.0.0

@freddieee you'll have to wait till the next release of the SDK and respectively Gaia.
