fixed JPF_.._Verify.registerChoiceGenerator() to not break and ignore the
transition if there are no choices, but to just return the provided default
value. Thanks to Pascal Kessell for reporting
added a .include_null option for the TypedObjectChoice CG. If it is set
(default) 'null' is included in the choice set
added a dedicated reg test for TypedObjectChoice, removed the one in
DataChoiceTest
