Added external jquery link to karma.conf.js, refactored geolocation_spec...

[Mike-Loffland]

[#48] is closed... But, Karma was still complaining:

Error: Bootstrap's JavaScript requires jQuery at http://localhost:9876/base/app/scripts/bootstrap.min.js?313da686ebbe387064f2d1899c64ea562b81eb40:6

• Added a https://ajax.googleapis.com/ajax/libs/jquery/1.11.2/jquery.min.js file reference into karma.conf.js

[Pull Request #51] Removed the $rootScope.$apply methods. But, this caused the geolocation unit tests to fail.

• Wrapped each assertion in a $rootScope.$apply in order to force Angular to digest the mocked getCurrentPosition since it's using the native setTimeout to emulate a promise
