Reproduction Steps

1. On a store with a subscription Order placed in the past that has been placed or renewed this month, go to LifterLMS > Reporting, "Sales" tab
2. Click Toggle Filters and select the Membership or Course for the Order
3. Choose a date range that covers one or more transactions for the Order and click Apply Filters
4. In a separate tab, edit the Order and partially refund a transaction
5. In the tab with Reporting, click Apply Filters again or refresh the page

Expected Behavior

"Net Sales" is reduced by the amount of the partial refund

Actual Behavior

"Net Sales" is reduced by the full amount of the transaction

Tech Notes

We should include transactions with both llms-txn-succeeded and llms-txn-refunded since a partially refunded transaction currently has the status set to llms-txn-refunded
