Change `runInThisContext` to `Script.prototype.runInThisContext`. (#8771)
Change `runInThisContext` to `Script.prototype.runInThisContext`. (#8771)

This actually changed ages ago, in Node.js 0.11 via
https://github.com/nodejs/node/commit/fd3657610e49005dfc778c3f060dbba0a34f286a
however the descriptive error message, which was previously
enabled with `true` as the third argument, was silently lost.

This reimplements the descriptive error message as mentioned in
https://github.com/meteor/meteor/issues/3200#issuecomment-289685677 by
@d-schiffner.
