K2 Scripting: fix order of arguments processing

and base class handling:
Since in K2 we do not distinguish between script arguments taken from
the base class and provided properties, we need this extra functionality
to preserve the argument order of K1 scripts.
This is a temporary measure, since we're going to deprecate base class
usage at some point (KT-60449), so the relevant constructor arguments
should disappear too.
