Re-look at GetElementHandlers

[PandaMagnus]

A situation was discovered that, depending on how the DOM is structured and how the locator is structured, using nth-of-type doesn't work. Multiple results will come back in the nth-of-type(1) scenario, and none for nth-of-type(2).

We should see if we can provide maybe an overload method or an optional argument for expected number of elements that accounts for this. Not sure how, but it would be nice if the method didn't just return one result and move on without any sort of notification that multiple results were found on the nth-of-type(1) scenario.
