LedgerResult Deserialization: Malformed Memos field

[nkramer44]

Prior to XRPLF/rippled@a5297d1, rippled did not validate the format of the Memos field in transactions. There are one transaction in ledger 7266368 that has a malformed Memos field that looks like this:

"Memos": [
    {
        "TransactionMetaData": {}
    }
]

This ticket may not be worth fixing, as it will require changes to Transaction that will be hard to make without breaking the API, and any fix would only apply to one transaction in a very old ledger.
