py-astroid: updated to 2.0.2

What's New in astroid 2.0.2?
   * Stop repeat inference attempt causing a RuntimeError in Python3.7

   *  infer_call_result can raise InferenceError so make sure to handle that for \ 
the call sites
      where it is used

     infer_call_result started recently to raise InferenceError for objects for \ 
which it
     could not find any returns. Previously it was silently raising a StopIteration,
     which was especially leaking when calling builtin methods.
     Since it is after all an inference method, it is expected that it
     could raise an InferenceError rather than returning nothing.
