Title: Make sure invoices without a UID are always raised

The fix in #281 introduced a UID for Eventbrite issues, which is working well. However, other invoices (such as ones coming from the member directory) have a uid of `nil`, which gets cast as `"nil"` when accessing Redis, so no invoices with a uid of `nil` ever get raised (with the exception of the first one). This fixes that.
