This line crashes. It's during construction of ScriptPromise::InternalResolver
in ScriptPromiseResolver, which is interesting... Have I not baked up my fake
objects well enough?

Toss ScriptState::Scope scriptScope(scriptState()); above this to scope the
local script object allocations - with that fix I make it as far as
~TestWebCache

And I found it. Thanks Josh, I'll be uploading a review ready version of this
shortly.
