Subject: [PATCH] Bug 16951: Fix Item search sorting

Caused by
  commit ac5a1bfececb5400a77f0ebad90181f5215d5a85
    Bug 16154: CGI->multi_param - Manual changes

The change was wrong, we wanted to retrieve a scalar (the string), not
an array.
We want to retrieve a string with the different column' names, not an
array of 1 element.

Test plan:
Launch an item search and play with column sort
