getLocationAbsUrl for Angular 2 apps fails to execute 'querySelector' on 'Document'

[cnishina]

getLocationAbsUrl relies on a document query selector which does not work with Angular 2.

lib/clientsidescripts.js:

var el = document.querySelector(selector);
  if (angular.getTestability) {
    return angular.getTestability(el).
        getLocation();
  }

sample spec:

    var url = 'http://localhost:3000/';
    browser.get(url);
    expect(browser.getCurrentUrl()).toBe(url);
    expect(browser.getLocationAbsUrl()).toBe(url);  // <-- does not work

error output:

1) test suite should navigate to the baes url
  Message:
    Failed: invalid element state: Failed to execute 'querySelector' on 'Document': The provided selector is empty.

Historically, the only reason we have getLocationAbsUrl is kind of a workaround for IE. You should be able to use getCurrentUrl just fine in Angular2, and generally prefer that.

Changing this to a documentation issue.

Ok about getLocationAbsUrl, but looks like he will get the same issue if he calls setLocation.
The error message says 'The provided selector is empty' because he is using useAllAngular2AppRoots() I suppose.
