[addProject] assets exported to wrong path

[sh-dave]

main project: khafile.js

prj.addProject('libs/subproject');

sub projects khafile:

prj.addAssets('assets/**', {
    notInList: true,
    nameBaseDir: 'assets', destination: '{dir}/{name}', name: '{dir}/{name}',
});

Converted assets will be written to ./build/libs/subproject/assets/... instead of ./build/debug-html5/
