Don't check url (by HEAD request) before navigateTo

Removed angular.scenario.Application.checkUrlStatus_ method and these tests:
* should call error handler if status check fails
* should perform a HEAD request to verify file existence
* should call error handler if status code is less than 200
* should call error handler if status code is greater than 299
* should call error handler if status code is greater than 299
