Make ExpandRecurringBillingEventAction SQL-aware (#1181)

There is some complication regarding how the
CancellationMatchingBillingEvent of the generated OneTime can be
reconstructed when loading from SQL. I decided to only address it in
testing as there is no real value to fully reconstruct this VKey in
production where we are either in SQL or Ofy mode, both never in both.
Therefore the VKey in a particular mode only needs to contain the
corresponding key in order to function.
