Resume tuning after updating search space with more hyperparameters

[wxie2013]

That’s actually what I did for a different issue in the following thread:

Correct way of using tuner.restore()

According to the source code comments, the restore() function is only for “”"“Restores Tuner after a previously failed run.”. If a previous run is not failed, then the restore() function will just printout the tuned result from the previous run.
