Bug 21455: Authority search options get shuffled around when you click on 'Search'

In the staff client, when you perform an authority search the
selected values for the 'Search all headings:' and 'Search
entire record:' options get shuffled around when you click on
the 'Search' button.

This patch fixes that.

Test plan:
1) Perform an authority search and set the 'Search all headings:'
   option to 'starts with'.
2) Click on the 'Search' button.
3) Notice how the 'Search all headings:' option is now 'contains',
   and 'starts with' has moved down to the 'Search entire record:'
   option.
4) Apply the patch.
5) Hit 'Search' again. This time the selected search options do
   not move around.
