generate new cosmos/osmosis zero-fee reference TXes

[mrnerdhair]

Overview

In #524, we disabled a set of failing integration tests. The reference data for these TXes contain a zero-valued "fees" field, which is now omitted by proto-tx-builder. This change should be compatible, but we need the tests updated with new, on-chain, successfully-broadcast reference data.

References and additional details

See 25c1e1c for the disabled tests.

Acceptance Criteria

• Tests are re-enabled and pass with freshly generated reference data
• New reference data comes from TXes actually broadcast and successful on-chain
