scrollToOffset broken

[sdboer78]

release: 2.7.0

frame.content.html:
if ('parentIFrame' in window) {
parentIFrame.scrollToOffset(1,1);
}

gives:
Uncaught TypeError: Cannot read property 'x' of undefined iframeResizer.min.js:8

Check:

parentIFrame.scrollTo(1,1) works fine!

Argh, that's a lesson not to refactor code when tired and a hole in the unit test for this bit of code.

Fixed v2.7.1.
