se getOrElse for getting the threshold of LR model
The `toString` method of `LogisticRegressionModel` calls `get` method on an
Option (threshold) without a safeguard. In spark-shell, the following code `val
model = algorithm.run(data).clearThreshold()` in lbfgs code will fail as
`toString `method will be called right after `clearThreshold()` to show the
results in the REPL.
