Google Analytics: API Update

[cxaviousb]

The Google Analytics package that this project calls has been updated in a backwards incompatible manner. These edits are updates to address these changes.

This API clash is currently causing users of ng-cordova to be unable to log properly in Google Analytics after fresh builds.

Note:

1. For an unknown reason (at least to me), a unit test is broken for $cordovaToast before I made any edits. Not sure what's causing it, but it should be pop up if retest your master branch as well.
2. This contains the same edits as Google Analytics: API Update #1392 which is based off the master branch instead, given the current release doesn't work with the current release of https://github.com/danwilson/google-analytics-plugin
