Request param from the url query string return string instead of array for param with multiple value

[quang-tuan]

When passing an array as search query through the param using the [uiPrams] everything work as expected where the param is returned as array of string. However, passing the search query through the url such as ?param=test1&param=test2 the app is returning a string (test2) instead of array of string.

Plunker example has 2 link where one is using the uiSref, the other one is using the href

I believe the issue is caused by this line in location.ts

loc.search = <any> (() => {
   let queryString = splitOnHash(splitOnQuestionMark(locSt.path())[1])[0];
   return queryString.split("&").map(kv => splitOnEquals(kv)).reduce(applyPairs, {});
 });

The applyPairs function return key, value assumed that keys are unique.

This will be fixed in beta.4: https://plnkr.co/edit/hZ2Lehs2IOxw1qdufPF4?p=preview

We're now using a wrapper around the "vanilla" location api from ui-router-core which properly manages arrays
