[BUG]: invoices without payment methods made in the past are always created as failed; they should be pending

[doctorpangloss]

Describe the bug

BillSubscriptionJob.perform_later([subscription], timestamp)

on seemingly any past timestamp show up as failed in the UI.

To Reproduce
Create a subscription with an expected payment date in the past. Create an invoice at or between that date and the current date. Observe the UI shows the invoice as failed.

Expected behavior
If payments are manual, the invoice should show always show as pending.
If payments are automatic and the payment period + grace period have not elapsed, the invoice should show as pending.

@doctorpangloss do you have any payments linked to this invoice? What's the status of it?
