Bug 12595: Search a patron by his/her firstname and surname

Before bug 9811, if you searched for "John Doe" and only 1 patron with
this firstname/surname existed, the patron detail page was displayed.

Now the result lists all patrons with ( firstname=john or doe ) or (
surname=john or doe). Which is quite annoying when you expect only 1
result.

Test plan:
0/ Create some patrons like: "John Doe", "Jane Doe", "John Smith".
1/ Search for "John Doe" in the patron search box
2/ Verify you got 2 results
3/ Apply the patch
4/ Search for "John Doe" in the patron search box
5/ Verify you are redirected to the right patron detail page.
