Bug report: Authz info broken for Kujira network

[dylanschultzie]

Prerequisites

• I am running the latest CosmPy version.
• I checked the documentation and found no answer to my problem.
• I checked the existing issues to make sure my problem has not already been reported.
• I have read the code of conduct before creating this issue.

Expected Behavior

When running an authz vote tx:

    msg = any_pb2.Any()
    msg.Pack(
        MsgVote(proposal_id=int(proposal_id), voter=voter_address, option=vote_option),
        "",
    )
        tx = Transaction()
        tx.add_message(MsgExec(grantee=str(authz_wallet.address()), msgs=[msg]))
        tx = prepare_and_broadcast_basic_transaction(client, tx, authz_wallet, gas_limit=300000, memo="Pitter Patter, let's get at 'er!"):
        submitted_tx = confirm_successful(client, tx.tx_hash)

A submitted tx response should resolve.

Current Behavior

Error that is thrown is: Failed to parse auth_info field: Message type "cosmos.tx.v1beta1.AuthInfo" has no field named "tip" at "GetTxResponse.tx.auth_info"

Here is the transaction is occurred on: https://github.com/fetchai/cosmpy/issues/new?assignees=&labels=bug%2Cunconfirmed&projects=&template=bug-report.yml&title=Bug+report%3A+%3Cshort+description%3E

The JSON contains a tip field that needs to be handled by cosmpy.
