closes #10773 - The refactoring is a substitute for `urlService.utils` used previously throughout the codebase and now extracted into the separate module in Ghost-SDK - Added url-utils stubbing utility for test suites - Some tests had to be refactored to avoid double mocks (when url's are being reset inside of rested 'describe' groups)
