Bug 35488: Open holds tab by default on opac-user.pl after placing a hold

1 - Place a hold on the opac
2 - Note after placing the hold the URL is:
    http://localhost:8080/cgi-bin/koha/opac-user.pl?#opac-user-holds
3 - Note the holds tab is not active
4 - APPLY PATCH and restart_all
5 - Try steps 1 - 3 again, this time the holds tab should be opened.
