Bug 14344: uninitialized value warning C4/Utils/DataTables/Members.pm

The condition for the assignment depends on $searchtype to be defined
and equal to 'contains'. So this change doesn't change the semantics.

-            if $term !~ /^%/
-                and $searchtype eq "contain";
+            if (defined $searchtype) && $searchtype eq "contain"
+                && $term !~ /^%/;

To test:
- Home -> Circulation -> Checkout
- Search for a user that does not exist (I searched 'whywouldthisexist') on the intranet interface.
- Look at the intranet logs
=> FAIL: you get "Use of uninitialized value $searchtype in string eq at.,,"
- Apply the patch
- Repeat the search
=> SUCCESS: No warning
- Sign off :-D

NOTE: Other pages are more forgiving. Tweaked test plan.
