Bug 33829: Fix add patron to patron list if PatronAutoComplete is off

When adding patrons to a patron list we get a JS error about undefined
variables. We can easily fix this problem by defining them even if the
pref is not set.

We are enabling the auto complete even if PatronAutoComplete if off.
