This patch fixes python/10805. When fields were being constructed, the 
convert_fields function was not checking if the type was a class before 
determining if it was a base class. Added a check to gate this behaviour.

Additionally, I started a testsuite for Python types. This suite only 
tests for this regression, but it can be expanded later, in separate 
efforts.

Cheers,

Phil
