Router not working with multiple query parameters with the same name.

Current behavior

Currently when going to a url with multiple query parameters with the same key the DefaultUrlSerializer is removing all but the last one from the url.

/something/route?room=a1&room=a4&room=a6

This link will be rewritten to:

/something/route?room=a6

Expected/desired behavior

The url should remain the same and keep all parameters.

Please tell us about your environment:

• Angular version: 2.0.0-rc.6
• Browser: all
• Language: Typescript

This pull request fixes the issue but it’s my first one - https://github.com/angular/angular/pull/11373

I would expect an array back.

I would at least expect some way of handling the use case of when we need to send an array as parameter (e.g. in faceted search), instead of “creating a magic string” and having to deal with parsing the it yourself. +1 for the bug report and pull request.
