Fix admin repository links and remove buttons

- Use $location.search() instead of window.location.search for URL
  params so cross-page links (owner, conference, search filters) work
  with AngularJS client-side navigation
- Add missing removeRepository() in both repos and user detail controllers
- Fix removeCache() spurious $scope.$apply() that caused digest errors
- Add confirmation prompts and list refresh after remove/cache operations
