Allow option with empty value

[javve]

Thanks a lot for a nice lib. I'm currently in the process of switching from x-select to ember-select-light and I found something I would consider a bug.

It's not possible to have an option with a value that is just an empty string.

<SelectLight @value={{value}} @change={{action "myAction"}} @options={{selectOptions}} />

get selectOptions() {
  return [{
    label: 'Nothing',
    value: ''
  },{
    label: 'Option 1',
    value: '1'
  }]
}

At the moment this will result in this:
