the logger verbose level is not maintained after unpickling it

[greenlymicael]

Describe the bug
The logger verbose level is not maintained after unpickling it.
If you check the verbose level saved in model.verbose, it outputs the value correctly, but

To Reproduce
Steps to reproduce the behavior:

1. Fit a model with verbose=logging.WARN (30)
2. Pickle and save to a file the fitted model
3. Unpickle the model
4. Check the model.logger_.getEffectiveLevel() and see that it's set as logging.DEBUG (10)

Expected behavior

The logger level should be WARN and not DEBUG
