AssertionError: Invalid child type when WSDL contains imports or includes

Any WSDL containing imports or includes will cause following error => "AssertionError: Invalid child type"
Sample WSDL to reproduce the issue => test/wsdl/strict/reproduce_issues_125_and_312.wsdl

Check: https://github.com/vpulim/node-soap/issues/125 (Almost a year ago)
Also Check : https://github.com/vpulim/node-soap/issues/312

I suggest those types of elements are ignored temporary until node-soap has some logic to handle them.
