Title: ui-select2 not working when combining multiple and ajax

I use the following config which use both multiple and ajax:

$scope.opts = {
ajax: {
url: "/....",
initSelection: function(el, fn) {},
multiple: true,
data: function (term, page) {
return { q: term };
},
results: function (data, page) {
return {results: data};
}
}
}

However, the component always render 'undefined' when an option is selected, and clicking remove on the 'undefined' seems to not do anything. After inspecting, it turned out that the $watch handler always be triggered before the handler of 'change' event of select2 element, and the current value at that time is a string value instead of an array causing the select2 data to be reseted.

I've made a minor update to fix this bug.
