message: Fix the issues with user logins
  Users are forced to login page when api throws 500 errors. Fixing so that they are redirected to login page only when they see 401 or 403.
diff: function authInterceptor($q, $location, tokenService) {
  return {
  responseError: function (response) {
  - if (response.status === 401 || response.status === 500) {
  + if (response.status === 401 || response.status === 403) {
  tokenService.removeToken();
  $location.path('/login');
  }
