Fix #10

As suggested by @OgaBoss

@MBach, @OgaBoss solution didn't work as-is in my case. I needed to just add the .vue extension at the end and then it worked!

import Collapse from './Collapse.vue'
import Item from './Item.vue'

export {
Collapse,
Item
}

@albertoantunes I think you might have some issues with how you load vue files. Usually, you don't need to put any extension: .vue, .js!
