Log message for revision 72381:
  Fix interfaces that subclass interfaces in persistent modules
  
  When interfaces in a persistent module subclass other interfaces from
  a persistent module, they then become dependents of the subclassed
  interface.  As such the DependentsDict needs to convert such
  interfaces to thier persistent versions.
  
  I added InterfaceClass to the values handled by the DependentsDict and
  updated the tests.
