[SPARK-19985][ML] Fixed copy method for some ML Models
## What changes were proposed in this pull request?
Some ML Models were using `defaultCopy` which expects a default constructor, and others were not setting the parent estimator. This change fixes these by creating a new instance of the model and explicitly setting values and parent.
## How was this patch tested?
Added `MLTestingUtils.checkCopy` to the offending models to tests to verify the copy is made and parent is set.
