Bug 21288: Slowness in acquisition caused by GetInvoices

The SQL query done by GetInvoices is quite slow on our production server,
taking about a minute.

In the query, there's this join:

  LEFT JOIN subscription ON biblio.biblionumber = subscription.biblionumber

but there's no index on subscription.biblionumber. Adding the index speeds
up the query so it only takes up about 3 seconds.
