Bug 35495: Open holds tab by default on opac-user.pl after cancelling a hold

To test:
1 - Go to the opac-user.pl page for a user with some holds and cancel a hold.
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. Now after cancelling a hold, the refreshed page should have an active hold tab.
