Milan reminded me about this today so I went ahead with it.

It turns out just the D-Bus service names need to be versioned, not the
interface names.  But the same rules for incrementing the version apply.

The new names are (with both versions at '0'):

   Bus Name:    org.gnome.evolution.dataserver.AddressBook0
   Object Path: org/gnome/evolution/dataserver/AddressBookFactory
   Interface:   org.gnome.evolution.dataserver.AddressbookFactory

   Bus Name:    org.gnome.evolution.dataserver.Calendar0
   Object Path: org/gnome/evolution/dataserver/CalendarFactory
   Interface:   org.gnome.evolution.dataserver.CalendarFactory
