Assert should compare same type

Nicolas Vuaille requested to merge nicolas.vuaille/paraview:PythonDecorator into master

In a python plugin using default_attributes on a vector property decorator, an assertion incorrectly fails because of a string to int comparison.

As a note, using the raw xml works as expected.
