Memo field not included in incoming payment transactions for the account activity endpoint

[Bogardo]

When making a request to the /v1/accounts/:address/activity endpoint to fetch all payment_v1 and payment_v2 transactions the memo field is not included for incoming payments.

Example

Get the activity for the address: 13iupFgtU2HKy9Yndfq58CfBvzNFqGuVrEid1G3QWAMhBTjf1R1 This should return all (paged) activity, which includes the following two transactions. One is an incoming payment, the other is an outgoing payment.

You can see that the outgoing payment includes a memo, and the incoming payment does not.

When you fetch both of these transactions from the /v1/transactions/:hash endpoint you can see that they both include a memo field.
