Bug 16429 - Going to circulation from notice triggers may change logged in branch

If you edit notice triggers and then use the "Checko out" tab from the
top bar, you may change your logged in library by accident!

Test Plan:
1) Disable the system preference CircAutocompl
2) Go to the notice triggers
3) Select the triggers for a library other than the one you logged in as
4) Use the "Check out" tab at the top to check out to a patron
5) Note your logged in branch has changed ( you'll need to refresh the
    page if the check out search took you directly to one patron ).
6) Apply this patch
7) Repeat steps 2-4
8) Note the branch no longer changes

Tested with both patches applied. Works as expected.
