select: Error in case of empty items array

[tormozz48]

Hello all. I found some strange code in select block which gives me error in case of empty select item array on select click.

_hoverCheckedOrFirstItem : function() { // NOTE: may be it should be moved to menu
        (this._getCheckedItems()[0] || this._menu.getItems()[0])
            .setMod('hovered');
    },

It is simple to understand that in case of empty array this._menu.getItems()[0] will gives error with message: 'Uncaught TypeError: Cannot read property 'setMod' of undefined'

@tormozz48 What do you expect when try to use select without options? HTML spec for native select tag says that it must contain at least one option element.

@tadatuta I think that this should be a problem of my app business logic, but not a block. As for me, the piece of code which was given has not any validations for empty options set case.

@tormozz48 can send a PR which will explicitly throw an error in such case?
