Conjure python types are not picklable

[JacekLach]

What happened?

#317 broke pickling of conjure types

>>> from ontology_metadata_api.ontology_metadata_api import RuleSetBinding
>>> binding = RuleSetBinding(bindings={}, rule_set_rid="some.rid")
>>>
>>> import pickle
>>> pickle.dumps(binding, pickle.HIGHEST_PROTOCOL)
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
_pickle.PicklingError: Can't pickle <class 'ontology_metadata_api.ontology_metadata_api.ontology_metadata_api_RuleSetBinding'>: attribute lookup ontology_metadata_api_RuleSetBinding on ontology_metadata_api.ontology_metadata_api failed

This is because:

>>> binding.__class__
<class 'ontology_metadata_api.ontology_metadata_api.ontology_metadata_api_RuleSetBinding'>

__class__ points to a reference that is not valid

Fix:

>>> binding.__class__.__name__
'RuleSetBinding'
>>> binding.__class__.__qualname__
'ontology_metadata_api_RuleSetBinding'
>>> binding.__class__.__qualname__ = binding.__class__.__name__
>>> binding.__class__
<class 'ontology_metadata_api.ontology_metadata_api.RuleSetBinding'>
>>> pickle.dumps(binding, pickle.HIGHEST_PROTOCOL)
