Model initialized with `skip_model_load` does not have a compiled path

[TobyRoseman]

Code:

import coremltools as ct

m = ct.models.MLModel("<path to saved MLModel>", skip_model_load=True)
m.get_compiled_model_path()

Outputs:

----> 1 m.get_compiled_model_path()

File ~/miniforge3/envs/prod/lib/python3.8/site-packages/coremltools/models/model.py:528, in MLModel.get_compiled_model_path(self)
    520 def get_compiled_model_path(self):
    521     """

    523 
   (...)

--> 528     return self.__proxy__.get_compiled_model_path()

AttributeError: 'NoneType' object has no attribute 'get_compiled_model_path'

Correct behavior: Return None without error.
