Allow onSearch to query empty string

As in the code, the search function only triggers when the input string is not empty

https://github.com/sagalbot/vue-select/blob/master/src/mixins/ajax.js#L42

if (this.search.length > 0) {
				this.onSearch(this.search, this.toggleLoading)
        this.$emit('search', this.search, this.toggleLoading)
      }

So when I enter a search query, then remove the query, it is stuck with the last letter, so I cannot query for all items anymore, thus no way to disable the search (the onSearch event does not fire at all).

Please remove this check or show a way to remove the entered search. Thanks!

I totally agree that this could be in the component itself. As a workaround, you can always use something like v-on:keyup.native="someMethod($event)".

Fixed in 3.0. The onSearch callback has been removed in favor of the @search event, which is called anytime the string changes, regardless if it is null.
