Restored original syntax

Restored original syntax in the specs as [it was in v1.2](https://github.com/mootools/mootools-core/blob/master/Specs/1.2/Element/Element.js#L246)


`Array.type()` is old MooTools and return boolean , not `'array'` (string)
[jsFiddle](http://jsfiddle.net/nYMWz)

Another solution would be to use `expect(typeOf(myElements) == 'elements').toBeTruthy();` but since this Spec is for 1.2 I supose its better to keep it's own syntax and not more modern code.
