fix(next): do not crash sub manage on canceled sub

Because:

- Retrieving upcoming invoices using customer and subscription fails for
  customers with a subscription set to cancel at period end.

This commit:

- Updates query fetching an upcoming invoice to always behave as if the
  subscription is not set to cancel at period end.

Closes #PAY-3290
