Changed Select#getValue() to return null if no element is set. This is what tests seem to be expecting but is at odds with the comment in Button (which this method overrides).

From button.js:
* @return {*} Button value (undefined if none).

I'm not going to attempt to reconcile the comments in Button and its behaviour at this time though.
