Bug 20763: AllowPurchaseSuggestionBranchChoice triggers error opac-suggestions.pl is visited without logging in
Some code executed in the script opac-suggestions.pl if the system preference AllowPurchaseSuggestionBranchChoice is enabled assumes there is a logged in user. If there is not, patrons will see the error "Internal Server Error".
Test Plan:
1) Enable AllowPurchaseSuggestionBranchChoice
2) Enable AnonSuggestions
3) In the OPAC, perform a search that will have no results,
click the "Make a purchase suggestion" link.
4) Note the error
5) Apply this patch
6) Reload the page
7) The page should load now!
