Fixes #1422

Fixes the Hardcoded Sigmoid value from -.5 to the value specified during training.

Let Microsoft.ML.Tests see internals of Microsoft.ML.Standard trainers to access trained model parameters for testing verification.

Thanks a lot for contributing this fix! Would you consider making a direct test between ML.NET and LightGBM using non-default sigmoid? We have a similar test here.

Thanks for your feedback @wschin ! I added a positive and negative test case for the case you mentioned.
