Description

Some ML Models fail when copied due to not having a default constructor and implementing copy with defaultCopy. Other cases do not properly set the parent when the model is copied. These models were missing the normal check that tests for these in the test suites.

Models with issues are:

• RFormlaModel
• MultilayerPerceptronClassificationModel
• BucketedRandomProjectionLSHModel
• MinHashLSH
