Bug 34094: Use DefaultPatronSearchMethod consistently

Bug 34094: Use DefaultPatronSearchMethod consistently

This patch updates the patron search bar and pages to default search
method to that defined by DefaultPatronSearchMethod system preference.

Test plan
1) Prior to this patch confirm that regardless of what you set
   DefaultPatronSearchMethod to, the search in /members/member.pl,
   members/members-home.pl and the search from the patrons search top bar
   all default to 'contains'.
2) Apply the patch
3) Confirm that the system preference now affects the default option for
   match type upon page load.
