Wrong parameter to ExhaustiveOptimizerv4.SetNumberOfSteps crashes Python kernel

### Description

This hangs a Jupyter Lab notebook and crashes IPython.
```
import itk
import numpy as np
import matplotlib.pyplot as plt
OptimizerType = itk.ExhaustiveOptimizerv4[itk.D]
optimizer = OptimizerType.New()
#optimizer.SetNumberOfSteps([5, 0]) # correct
optimizer.SetNumberOfSteps(5) # incorrect
```
### Expected behavior

A soft type-error that doesn't crash the kernel.

### Actual behavior

It hard crashes.

### Versions

ITK release branch, Python Wrapping.

### Environment

ipython 7.13.0
jupyter-lab 1.2.7
Python 3.7.6

ITK release branch built locally and referenced using WrapITK.pth
