AttributeError not being raised in SWIG 4 when making an improper assignment in input processor #1288 (#1603)

Browse Source 
In convert_swig added a line to override the __setattr__ function. This makes
the new SWIG behave like older SWIG versions. the _swig_setattr_nondynamic_instance_variable
function is provided by SWIG and is similar to what our version of _swig_setattr_nondynamic
above is. If later we need to override _swig_setattr_nondynamic_instance_variable it can
be done the same way as before.
