Inline ShouldTriggerRefill() in its only reference as a lambda

Previously, some skip reasons existed outside the function (the one for
JS modified exp-dates). In an effort to unify this, this CL makes the
function a lambda and moves all skip logic there.

The advantage over keeping the function is having one less function with
optional parameters and not having a function who seems constant
actually modify the refill context.
