Bug 20456: (follow-up) Fix number of subscriptions and position display

TT variables needed to be adjusted because of changes from bug 20400.
Also: while we want logged_in_user in OPAC, we don't want that in staff.

1) Check the right number of subscriptions is displayed on top of the table
2) check the right position number is display for the routing list
