Remove .tentative from setHTMLUnsafe-runScripts test

[noamr]

See whatwg/html#12495

I think we need more coverage. E.g.,

• unsafe + sanitizer that removes the script element.
• multiple script and style elements with the script elements trying to observe the order in which state gets initialized and things are run (cc @domfarolino)

We should also add a test that ensures Document.parseHTMLUnsafe and Element.prototype.setHTML don't look at this member (throw if the binding layer attempts to get it).

@hsivonen might also have some ideas for this, perhaps?

Added tests to that effect. Happy to add more coverage that people think would be useful.
