What is the difference with the tests implemented in https://github.com/onnx/onnxmltools/blob/master/tests/sklearn/test_TreeEnsembleConverters.py?

Ah, I missed it. Also the multiclass LightGBM classification seems to have some issues. When I try to use it, i encountered into problems, that's why I want to add the multiclass test. Since I can't find a LightGBM test file, then I added one.

So I changed the PR to just add the multiclass tests. Actually, the problem I saw does not repro anymore..

Any update of this PR, do we still need it?
