/v3/transactionsByMessage returns incomplete out_msgs

[slavikus]

When querying the transactions through /v3/transactionsByMessage endpoint, where the transaction has multiple out msgs, the resulting structure only contains one element in the out_msgs structure.

For example, querying for

{
            direction: "in",
            msg_hash: "JP18/POtau3Qtz3nO6wVVgImitCzlkxZnvqi8GZFCN8=",
            limit: 1,
            offset: 0
}

returns

This issue persists for several days for any completed transactions we try to query for.
