LP#1548869 KPAC hold results screen not displaying complete info

The getit_results.tt2 page was not displaying item title after
hold placement or after adding to a list. It was also not pulling
in the item id (which was needed for navigational links back to the
record) and was not pulling in the list name after adding an item
to a named list.

This patch adds some logic to prevent subroutine conflicts, adds
missing parameters to a function call, and corrects a variable name.
