Payment Activity Card shows an error for new accounts: Error retrieving payment activity data.

[Jinksi]

Describe the bug

An error is shown when rendering the Payment Activity Card for new accounts who may not have added a deposit destination or verified identity.

The response from /wp-json/wc/v3/payments/reporting/payment_activity:

{
  "code": "wcpay_invalid_currency",
  "message": "Error: Invalid currency.",
  "data": null
}

Tip

See server endpoint /reporting/payment_activity handler here

To Reproduce

1. Onboard as a fresh WooPayments account. Don't add a deposit destination (bank account) or very user identity yet.
2. Purchase a product to bring Payments → Overview total balance > 0.
3. Enable the feature flag: wp option update _wcpay_feature_payment_overview_widget 1
4. Visit Payments → Overview.
5. Notice the error in the bottom-right. Error retrieving payment activity data.
6. Notice the Payment Activity Card amounts are incorrectly rendered as 0
7. In browser dev tools, notice the response from /wp-json/wc/v3/payments/reporting/payment_activity matches the error json response above.

Screenshots

Expected behavior

For new accounts, the Payment Activity Card amounts should render with the correct amounts and without errors, or not render at all.

Able to replicate the issue.

Tested with an account not properly onboarded.

When there is no transactions, i.e. `lifetime_total_payment_volume' is 0, seeing the empty screen as expected

We can skip adding payout account, but place orders so that the `lifetime_total_payment_volume' is non-zero, the API returns error and the values are 0.
