Duplicate selected values after multiple re-setting choices

Hi, thank you for the cool widget! found a bug: setChoices with replaceChoices = true and preselected choice in the data leads to nonsense duplicated value:

<select multiple></select>

const element = document.querySelector('select');
const choices = new Choices(element);

choices.setChoices([
  {label:'Choice 1', value:'1'},
  {label:'Choice 2', value:'2', selected:true},
  {label:'Choice 3', value:'3'},
], undefined, undefined, true);

choices.setChoices([
  {label:'Choice 1', value:'1'},
  {label:'Choice 2', value:'2', selected:true},
  {label:'Choice 3', value:'3'},
], undefined, undefined, true);

You can use .clearStore() as temporary solution

Hey - looks like the selected choice isn’t being cleared. Thanks for raising
