Substance Painter 10.1 Python JS API does not support optional arguments

Starting in Subtance Painter 10.1 suddenly it seems that the `'alg.mapexport.getPathsExportDocumentMaps` javascript command requires the `stackPaths` argument which has always been optional and is still depicted as optional in the documentation:

For example this fails:

```python

substance_painter.js.evaluate('alg.mapexport.getPathsExportDocumentMaps("export-preset-generator://viewport2d", "/path/to", "png")')

```

Stack trace:

```python

RuntimeError: TypeError: Passing incompatible arguments to C++ functions from JavaScript is not allowed.

At:

C:\Program Files/Adobe/Adobe Substance 3D Painter/resources/python/modules\substance_painter\js.py(56): evaluate

<string>(2): <module>

```

But this works:

```python

substance_painter.js.evaluate('alg.mapexport.getPathsExportDocumentMaps("export-preset-generator://viewport2d", "/path/to", "png", [])')

```

Even though the first command worked fine in Substance Painter 10.0 and below.
