Ok.  Figured it out.  This is a cautionary tale.  If you are using
your own version of SearchableModel beware the updates.  You can miss
something.  ;)
I didn't have this line (from 146 in SearchableModel)
self._Entity__unindexed_properties = frozenset
(kind_or_entity.unindexed_properties())
This was added May 8th in r56 of the file.

I'm going to find a better way of having a modified SearchableModel
because I bump my head on this every time there is a change upstream.
