Clean up paginated URL generation
refs #5091, #6612 - unify getNextUrl & getPrevUrl into getPaginatedUrl - ensure that it can generate a prev, next or exact page no url - ensure that it can figure out the base url - use the same code from the page_url helper - refactor the tests to ensure there's 100% coverage Following on from #6612, this ensures that pagination always works regardless of whether the channel is default or custom
