* This patch builds on core functionality provided in
Ied0295feab06027a8df885b3215435e596f0353b.
* This removes any nowiki wrappers present in unstripped text
(which there would be for preprocssed nowiki tags) which mimics
the effect of procssing nowikis in core when generating HTML.
* Updated lua tests to verify the new expectation.
* A previously failing parser test added to test T272507 now passes
and has been re-enabled.
